No, reverse breakdown voltage of common Schottky diodes used in power circuits (i.e. with average forward current rating greater than half an amp or so) typically ranges from 20 volts to 100 volts. There are 150 V power Schottky rectifiers on the market. Silicon carbide Schottky rectifiers up to 1200 PIV rating are made but they are quite expensive. The 600 PIV parts would be useful in active power factor correction circuits. If I were still designing that sort of stuff I'd be considering them. The reverse leakage current can be an issue in some applications. Schottky diodes intended for signal use and with low reverse leakage do exist. Hewlett Packard used to make a range of them. I don't know if any of that line is still being made by the current owner of that former HP division.

Thanks a lot for the video.

The last part about solar panels is not quite demonstrated properly because the bypass diodes are connected across each individual CELL of a panel, so as to bypass any cells of the overall panel that may get shaded by something like a tree or something at certain times of the day. It wouldn't be nearly as effective if the diodes were only connected across entire panels. Each cell in a solar panel produces about 0.5-0.6 volts in full sun, but goes down very quickly if shaded, so a panel that is only partly shaded will benefit from having ONLY the individual cells that are in the shade bypassed, and still be allowed to have the cells that are still in the sun producing power.

The Owner of the Car,Bert,said that we shall be alerted,because we are supposed to see something very rare.... Bert was right, there it was.Golden glowing. This was fascinating Never before have we seen such a Night glowing goldyellow gigantic wessel. Our Chauffor put the foot on the gaspedal. The Car motor was not quite tuned,ignistion And therefore we just was in speed,some 72 kilometer/per hour. Bert was keen on Study the under of the Gigantic Wessel. Just before we where about to reach the North side of the Tunnel,aproximate 30-40 meter,before outside the tunnel and on the South side of Bridge of Nötesund there was two sound,clang and clang,we hear as the window of the car,was down ,too be able to hear sound of the totally silent enourmos wessel hoovering some 50 meters above Sea Level..... Later we heard a withness tell,that he had taken a rifle,and shot two sharp ammunition under up of the Wessel. That was the exponation,clang + clang,underneath this Wessel... Glass Metal is 50 times stronger than ordinairy Metal or Stone. But anyhow,fraction of seconds Thereafter,20.13 in this Evening,in a very strong white,Sonoluminiscence flash that move Easterly directions with an immence acceleration,that no living thing could have a chance to survive. My beliefe is that we saw a TIME-travel... Withness saw 5 or 6 white Flashes along the pathway of this Wessel,at this time 20.13 20.04 o clock this Wessel came out of misty fogg,just materialized, 3 children aged 7 year old girl,and two cousines,about 9 year old,told us that they tought it was the Moon. They realized that it was not the Moon. This came to their attention,as they saw the pattern under this Wessel..... So this all happened this November evening. There are more details.Houses went dark,all electric devices stopped working,because of this Electro Magnetic Pulse. There was also seconds later,a big rubyred glowing cloud,in Eastern direction,it was very special movements,hard to explain. And seconds later a big dark blue NATO-star,it was only there for 5 seconds,and when it nomore was glowing,the Ruby Red Cloud went gone.There was as nothing have happened. Dark and somehowe terrific,like in Cinema. But this was a genuine UFO. NOTHING about it in the news. Not in Television,not on Radio,not in Paper News.1972 i wrote to Elvis Presley about it. No answer.But years later i got a letter from Bill Clinton. This ought to be told the children that UFO is from the Future Earth,visiting back in Time.

@@williambock1821 In many applications the primary advantage of Schottky diodes is their very short "reverse recovery time." The video touches on this but doesn't explain it well. When the voltage applied to a diode is suddenly changed from the "forward bias" to the "reverse bias" condition (that is, from the anode being positive with respect to the cathode to the opposite), it does not stop conducting instantaneously. Ordinary silicon PN junction power diodes take quite a long time to turn off - their "reverse recovery time" is long and quite a lot of charge gets through. It has to do with getting "excesss carriers" out of the junction region. This is of very little concern in low frequency circuits such as rectification at AC mains frequency. When you get up into the frequencies of switchmode power supplies, which these day can range from around 50 kHz to 1 MHz or so (100 kHz is quite common for high power switchers), the reverse recovery time and charge becomes a problem. Ordinary silicon diodes would cause a lot of power loss. There are "fast recovery" and "ultrafast recovery" silicon PN junction diodes available that work much better. Schottky diodes have even shorter reverse recovery time. The other advantage is the lower forward conduction voltage, as described in the video. Sometimes that isn't important, but it is in lots of applications. At moderately high currents (a few amperes to a few tens of amperes) a silicon PN diode may have a forward voltage of around 1 volt. A comparably-rated Schottky diode might have a forward voltage of about half that. At 20 amperes, half a volt difference is a 10 watt difference, and something that has to be considered in real circuits. In power supply "ORing" circuits the forward voltage can be a big concern. There aren't many Schottky diode with reverse voltage withstanding rating of more than 100 volts, whereas silicon PN diodes can be had up to 1 kV. There are Schottky diodes with much higher reverse voltage rating on the market but they are expensive. In general, Schottky diodes are quite a bit more expensive than similarly-rated PN diodes. Schottky diode "reverse leakage current" (current that can flow when the cathode is positive with respect to the anode) tends to be substantially higher than in silicon PN junction diodes. This isn't a big deal in lots of applications but it can be in some. Even the reverse leakage current of a silicon PN junction diode can be a significant issue in some low-level precision analog circuits.

Modern very fast silicon diodes are now available with minimal leakage current. Thus, today the Vf at load are the only issue left, and it is getting lower for the silicon diodes ( at load).

Electrons flow from negative towards positive. Hence the lined side of the diode receives electrons and spits them out the back, this is called forward biased. In a schematic, electrons flow against the arrow point.

I have had stupid arguments with idiots on KZread that seriously thought that we should just change over night to only talking about electron flow and making that the direction of current. Many people become confused between the two. It's best to leave out mentioning of electron flow unless explaining the internal operation of semiconductor devices and valves.

It doesn't conduct in both directions as long as the maximum reverse blocking voltage rating isn't exceeded. It behave like a silicon PN junction diode in terms of forward conduction (anode positive with respect to cathode). However the reverse "leakage" current of a Schottky diode is typically higher than for a comparably-rated silicon PN diode. This leakage current is too small to be of much concern for rectifier use, but it can be a significant in other uses such as low-level analog circuitry. There are small Schottky diodes made specifically for small signal applications. They are typically designed to have very low reverse leakage current. There are many silicon PN junction diodes with reverse voltage withstanding (blocking) capability up to 1 kV. It is easy to make them. Most Schottky diodes have a reverse blocking voltage rating of 100 volts or less. It is possible to get types with up to about 150 V reverse blocking rating, but there aren't many choices. There are types made with silicon carbide that can block up to 1200 V in reverse but the forward voltage is higher than that of a silicon PN junction diode and they are expensive. They are still very useful in some circuits because of their very short reverse recovery time.

Max surge current is 30 amps. So yes it can handle high current transient spikes. Not everything in electronics is straight DC bro. And diodes are often used as clamps to dissipate spikes, like from inductive kickback.

A 1N400x is sufficient for 50 to 60 Hz and has a threshold of 0.6 to 0.8 Volts. The range up to 1 Amps is to be calculated. A Schottky diode is faster but cannot withstand reverse flow well at higher voltages. Then a stupid 1N4007 is more robust. I want to point out the UF400x series, a Schottky that in many cases replaces a 1N400x.

The 1N4148 is a silicon PN junction diode optimized for "fast switching." As long as you can live within their current and voltage ratings they are pretty decent all-round compromise diodes. The reverse recovery time is short (4 ns, iirc) and their reverse leakage current is tolerable in lots of applications. If you need very low reverse leakage current there are much better diodes (the collector-base junction of a transistor like the 2N3904 has much lower leakage but is on the slow side; the base-emitter junction leakage is even less and is faster but the reverse breakdown volltage is around 6 volts)

Low prv some reverse leakage . High forward current low forward voltage.

Even in pure semiconductors, there are something we called hole currents which go the opposite direction to the electrons. So in conventional circuit calculations, we ignore whether it is the flow of electrons, ions or holes and just assume it is positive charge flowing from positive terminal to negative terminal for the sake of simplicity.

Search schottky diode construction

I have a circuit with a BJT transistor in it. It is a hydraulic selector handle that opens a hydraulically powered cargo door. Moving the handle in either direction turns on the electric motor. The handle has three positions, 1) Open 2) Off 3) Close. The handle ports hydraulic pressure to either the open or close position, and in either open or close it simply turns on the hydraulic pump motor. The electrical connector has three contacts, A, B, and C. There is a transistor symbol between A and B with C appearing to be unused. However one of the legs of the transistor appears to also be unused. It's not readily apparent from the drawing whether the one leg is used or not. My question is.......how can I test the selector handle electrically to see if it is functioning correctly? I mean.....in actual operation 28V dc is connected between contacts A and B and sent downstream. But when I move the handle in either the Open or Close position I get nothing on my meter no matter how I connect them to the contacts. And for the record, yes the handle is known to be good. But we couldn't be sure in the early stages of troubleshooting the door circuit. I'd like to know how to test this selector handle assembly to avoid changing it unnecessarily. Is there some sort of signal coming in the C contact that enables the transistor to pass the 28 volts between A and B ? So in other words, would I need to put some sort of voltage on the C contact in order for my meter to read continuity between A and B when the handle is moved to either Open or Closed? Thank you.

They are there almost entirely to protect a panel that might be shaded from having current driven though it by other panels that are receiving normal illumination. They rarely do anything useful in terms of power delivery, especially in an array where you have both parallel and series connections of panels.

After watching this video, one question stays stuck in my head... why I would not use a Schottky diode instead of regular diodes anywhere where a diode is needed (a regular, not a zener of course)

Since they are half metal, they have a low reverse breakdown voltage. Diodes are commonly used as a way to protect against reverse polarization, so there might be cases where Schottky diodes won't be helpful against reverse polarization (edit: i.e. high voltage circuits). Also, they are more susceptible to static discharges, which are more common than they seem (after working with PIC microcontrollers, I learned that the bad way :p).

If you have ever built a high-speed electronic device, you would know. Get out there on the bench and try some things.

​@@foobarmaximus3506Right. Her needs to use house oscilloscope to actually see the difference on the screen.

Why not to use only the Schottky Diodes ?

Cost. A regular diode is enough for frequencies less than 1kHz

Schottky diodes have much lower reverse breakdown voltage and higher reverse leakage current. Hence it is better to assess whether a normal diode or a schottky diode is better for the specific application you're looking at

Higher price and more complicated production process compared to a standard diode, unnecessary fast response time, higher current value, etc. There's a brunch of reasons

What is an “alternand?” As an electrical engineer, I have never heard this term used in describing sinusoidal waveforms, of anything. It isn’t in any dictionary.

Perhaps he means this? It still seems to be an incorrect usage. en.m.wikipedia.org/wiki/Electrical_alternans

Is a schottky diode the same as a fast recovery diode?

Features are slightly different.

This is narrated by a robo-narrator. That is consistent with the shottky diode being referred to as a "shock" diode around 4:57 and as a "choke" diode at 7:43. They have glitches like that.
