What are the Types of Transistors?
At the beginning of the 20th century, when computers began to be produced, they were gigantic. Today, however, there has been the discovery of transistors that make them small enough to take them on our knees and fit them in our palms with phones or tablets. In addition, thanks to transistors, processors that offer much faster operation have been developed. A transistor is an electronic circuit element that regulates current or voltage flow and acts as a switch or amplifier for electronic signals. It was invented in 1947 and quickly replaced the vacuum tube as an electronic signal conditioner. It consists of a layer of doped semiconductor materials such as silicon and germanium, each of which can carry a current. The subject of this video is not the structure and history of transistors, but after a small introduction about transistors, we can move on to our main topic.
You may know or have heard of transistors such as BJT, MOSFET, JFET, NPN, N-Channel and many more. But you may have trouble distinguishing them. If so, this lesson is for you. At the end of this video, we will basically learn that all three pins circuit elements are not transistors, how transistors are classified and how we can distinguish them.
Transistors are classified into two groups, BJT and FET. These expressions come from abbreviations formed from the initials of their English names. BJT comes from the acronym Bipolar Junction Transistor while FET comes from the abbreviation Field Effect Transistor. The task of both transistors is to provide current control or voltage amplification as a switch. If we talk briefly about the differences between them, BJTs control current and current, while FETs control voltage and current. BJTs are quickly affected by temperature, while FETs are less affected by temperature. As such, BJTs degrade quickly, while FETs are more durable and long-lasting. Therefore, BJTs are generally preferred in low-current hobby electronic applications, while FETs are mostly preferred in low-voltage commercial applications. Also, BJTs have a low switching speed, while FETs have a high switching speed.

why couldnt these other dudes do what you just did 💁♂️🤦♂️I appreciate you bro
Thanks I might have absorbed some of that information in my sieve like brain, hopefully

Molto bene, chiara esposizione !
Thank you😊
Thank you
Can any one tell me about GT30G124. Every datasheet I found for it is incomplete
thank you kindly because they all look the same at times

Great video. Let me help you make it better. Instead of saying "Take it on our knees" (nobody would say that) you could say "Use them on our lap" or "Rest them on our knees"

"take it on your knees" > " blah blah blah knees" ....sorry im a dick
people barely talk about 5 pins voltage regulators , especially SOT23-5 . SOT23 is the package type and 5 the number of pins . Sir , could you make a video about SOT23-5 and six pns , and how to use them ? I came across these componant when trying to fix a dead laptop , and I don't know how to check them , because we are used with two or three pins components , I'm sure many people face the same problem

I will try to do research and make a video 🤙
TY
Is there any way to remember the direction of the arrows when looking at schematic transistor diagrams? There seems to be no consistency when comparing NPN's of different classes. Does the direction of the arrow signify direction of conventional current? If so, why does the arrow direciton of NPN JFET's differ from that of NPN MOSFET's?

Hi Unfortunately there doesn't seem to be a way to keep it in mind. In BJT and JFET transistors, the arrow direction is relative to the conventional current direction. But in the MOSFET transistor, it's the opposite.

THIS IS WHY I STOPPED LEARNING THEORY SIDE DURING MY STUDENT LIFE . CONVENTIONAL , CURRENT IS SAID TO BE OPPOSIT TO ACTUAL CURRENT , ANOTHER CONFUSION FLOW OF ELECTRONS AND FLOW OF HOLES IN OPPOSIT DIRECTION , THERE ARE LOT OF CONCEPTS DIFFERENT AUTHORS EXPLAIN DIFFERENTLY AND MADE A MESS OUT OF IT . THEN AT A POINT WE HAVE COMPROMISE . AND MUG UP TO PASS EXAMS .
And isnt it true that current on a battery marked + is actually populated with more - electrons. ?

Well, they say opposites attract
The Unijunction transistor has been left out ( eg : 2N2160 ) , this has an Emitter and TWO bases ( b1 and b2 ) .... this handy little device is great for making pulse trigger circuits ( like a musical metronome , with a small loudspeaker as it's output ) ... they cannot be used for linear amplification ... modern types are called programmable Unijunction transistors ( PUT's ) ....... DAVE™ ............
you are so geneos
You forgot FJB
