Do you have a NPN transistor and you are not sure how to test it? I will show you a simple way on how to test your NPN transistor with a multimeter. After you follow how to test a NPN transistor, you will know if you have a good or bad NPN transistor. You will also know how different NPN transistors packages look like. You will also know how a transistor work.

I can now test transistors with confidence after watching your informative video, thank you.

@lornespry 4 месяца назад

A most excellent presentation. Very clear and beautifully presented.

Thanks. Helped me verify the 2SC2555 from my PP-7B power supply is good.

Hi, is this method for the transistor on the board connected to the battery or desoldered? Regards

@SineEyed 4 года назад

When testing an unknown BJT, the base pin (of both NPN and PNP) is easy enough to determine; but how do we distinguish which pin is the collector and which is the emitter?..

@mankeil4468 4 года назад

Usually, just use the part number to search up the datasheet. If it doesn't have a part number you really can't even know if it's a transistor or something else (as the same kind of packages are used between a variety of components)

@carlosgaspar8447 3 года назад

one voltage drop should be slightly different from the other (google search).

@serviteccompletojimenez8995 Месяц назад

So, collector and emitter are giving me lecture (both positions), and I have a question, is it common that these type of of transistors manage the signal of 12 volts that activates the relay in order to make a motor work? By the way I already tested the relay and it is ok, but no 12v signal, suspicious #1 NPN transistor!

@denisprudhomme8169 4 года назад

thank you,,,very good explanation,,

@riskianugrahmulia5776 13 дней назад

Does this test method apply to transistors installed on the PCB?

@electronictech785 12 дней назад

yes, but you also have to take into consideration of circuits that are in parallel to the transistor which can lead to misreading.

OL is for open line

@kychemclass5850 Год назад

Isn't it the current through the base of a BJT that matters, whereas MOSFETS its voltage?

@mahasaravana1169 2 года назад

Kindly post video for PNP transistor also

@yaseenhashim8538 4 года назад

Awesome excellent thanks beautiful way

@spark69jols Год назад

Sir can I ask what kind of smd Transistor with yhe marking of

@spark69jols Год назад

Marking of NB AB

@paolod853 Год назад

Wow

@briang.7206 2 года назад

Get an M tester they cost about $7 to $10. It can test transistors and lots of other things.

@Pumpkin_Fart Год назад

WHY the 0.3V to 0.7V? Why these two min and max readings?

@mikegaskill6347 Год назад

make it so, you can read the multimeter to see what the diode setting is...for those that are not multi meter savy. please

@shyammohabir8283 Месяц назад

isn't one test is missing - Black Led on Base and Red on Collector and Multimeter should give you an "OL" Over limit reading

@FlannelGuy_1978 2 года назад

Very Informative Thank You -- This video was a bit slow, so i set playback at 2X Speed -- much better!

@James_Bowie Год назад

Writing/typing out each letter at a time is time wasting and annoying. Just print the line and get on with it!

@Ocean_breezes 7 месяцев назад

Agreed. After watching for 15 seconds, I had to exit the video

@lornespry 4 месяца назад

For some us morons like me, the rubbing out gives us time to absorb and try to put things into long term memory.

@sainicomputers61 3 года назад

Worst backround sound

@Pumpkin_Fart 2 года назад

What is with the fake drawing? It's off-putting. Are you "Thing" from the Addams Family?

@Pumpkin_Fart Год назад

Don't forget to mute your tv

@victorysonics6564 3 месяца назад

Painting makes it painful to watch. Waste of time.

@raptorswire7212 3 года назад

you know why nobody does the hand drawing animations like this? Because it is annoying...original, but not useful in a tutorial really

@sunshinetorricelli1317 4 месяца назад

Worse tutorial ever.

@lornespry 4 месяца назад

For some of us, this pedestrian approach is exactly what we need. And of course, you didn't need to watch it.
