As soon as you said you pulled the npn transistor from a circuit, I knew it was a npn transistor since they are the most used in any given circuit

Fine tip. Thank you friend. Briefly the 2 outer legs are either P's(+ve) or N's(negative). So if you test them with their proper polarity by the Meter they should give the same readings as in the beautiful Video here.

good job...now I have a clear idea of what is PNP and NPN...thanks a lot...🙏🙏🙏

Thanks for the video it helped me score good in my lab exam. thank you once again.

So simple, yet I had no idea. Thank you. *Subbed*

well explained and easy to understand even for a total novice. thanks

*Summary of how to identify if a transistor is NPN or PNP:* PNP: base is negative. NPN: base is positive. *EDIT: An easier way to remember!* PNP: Positive-Negative-Positive NPN: Negative-Positive-Negative

very nice explanation , from Mumbai India

Thanks for putting a community together... A direct link on the vdo for your FAcebook would help... Great Job !

Your a lifesaver thanks so much I was always blowing transistor s before

thank you very clear just what i was looking for

Thank you for your explanation of how to figure which was which. It helped me greatly once I turned my Multimeter from Resistance to Diode. (It's the same setting on the selector, I just needed to press the Alt Function button). Taken me 10 minutes to notice that booboo.

Good description, thanks.

Good demo, thanks for sharing!

I have a transistor when I connect negative lead to left and positive lead to middle and right I get reading then what type of transistor it is?

It may show up as a PNP with the diode test, but unless you know for sure that the TO-92 package is standard, the collector and emitter could be interchanged. Looking up the number may be necessary to confirm which is which.

Very nice understanding sir. Good information

I have a question. Please help me with this. My machine works on pnp sensor but due to some problem the sensor got damage now at the current time I dont have a pnp sensor but a npn sensor. Can I use npn in place of pnp using a relay if yes please let me know how to do the wiring

So nice thanks the world's best teacher

if i want a 38 mhz pulse EMF what do i go for?

1:32 Is that same as continuity? And how do test it if the center pin is not the base?

great.. informative enough!

please,can you tell or show a technical approach to recognise which pin is the collector and which one is the emitter. thank you.

Thank you, I’ve been looking for not Indian videos.

thank you ! really for this information :)

Nice info, thanks :)

Informative video, Thanks

Hey, good tutorial. Sorry, dont do social media. Will do similar experiment with pre determined transistors, NPN, PNP, 2N3904(npn), and, 2N3906(pnp). From what I have learned, can sort out salvaged transistors without data sheet. Thanks, C.

Informative - Thanks.

this is really an informative video for begginers like me

Does the value on the multimeter tell you anything specific about the transistor?

Thanks man I need to learn this for my test wish me luck 😂🙏

great. you have solve my problem... thanks

Why cannot i find that page of power trace electroincs??????????????

What happens when you put the test leads on the 2 outter pins????

Good. Its really informative. :).

You rock man! I always take the time to look up the serial number of each transistor which is time consuming. This is much quicker! I appreciate your information. Take care!

Great video!

how can you tell with broken parts?

Thank u so much wao finally i got it how to identify them thank u

Good job, thanks man

Very informative. Thsnks

Good video. Thanks

thankssss bro very easy as way transistor chack for NPN/PNP

thanks for the help man!

Thanks that helped :)

THANK YOU, DUDE!

thanks! Sweet vid

thanks a lot now i can differentiate them

Good job, thanks, :-)

emitter is also to the right on both transistors as was tested. emitter is always a little higher out of circuit. great job keep up the good work and the base is not always in the middle. what determines that is where it was made. japan Europe usa etc. 73 kf4gyp Ray

thank you .you have helpt me

very nice video. ... which device r u using to identify the npn or pnp transistor

thanks a lot for this video

You could add that the lower voltage is representative of the collector and the higher one is the emitter...just to save time and questions.

Sir nice your tech i like that.

help full video thanks very much

How to find emitter and collector?

nice..thanks a lot

Thanks for helping

Thank you. Can you please show us how to build a solar light with darkness detctor

The problems from your video is which one is collector and which one is emitter? how do you identify collectors and emitter by multi tester ?

@migueljimenez8594

You missed the collector and the emisor identification.

@ronand.ronnie1193

iirc base terminal should be the same as emitter

What's each application ?

How about collector and emitter pins? does it matter which of the two p pins of the pnp transistor work as collector or emitter? Why? Thanks

@markanthony7184

7 жыл бұрын

It does matter yes, normally the forward drop between the base and emitter is slightly greater than the base to collector due to the slightly higher doping of the base to emitter junction, so you can find out which the collector and emitter are by knowing this.

thank you very much !

very helpful for a newbie

+Charles W Harris Jr Not all BJTs have the Base lead in the middle on the package. They only have to be internally connected to it. Depending on how the manufacturer makes and assembles the transistor casing determines which external lead is which.

How is if don't have multimeter?

i find my transistor burned it give nothing how ican know his type

it really help!

D1651 data sheet says this is a npn transistor but when tested its a pnp + - + i get readings - + - i get no readings and testing more on the two outside leads + - + i get current

Very useful. I'd also like to know how to identify if a transistor is bad or good

@jameshanley9102

npn base positive emitter/collector negative should read 0.7 volts reverse the leads should be open transistor is good, pnp base negative with respect to emitter /collector 0.7 volts reverse leads should give open ,if any of the tests should read low or 0 volts drops the transistor is knackered.

How do you find out witch is the collector or the emitter?
