In this video we look at Darlinton Transistor pairs. This is where two or more transistors are used together to multply their gains.

Everything's not perfect in the real world? I'm devastated and informed. I didn't realize a darlington pair would amplify the gain that much, WOW! Thanks Paul good vid.

Finally, a non-curry video about this

Great show once again i just like when you teach about Transistors and mosfets and IC s I can listen to you talk about them all day I learn something new evreytime thank you keep them coming .

@pavan1685 2 года назад

Thanks for knowledge sir

Ive actually been using the Darlington Array in all of my projects. But sometimes i use an led for reversed bias between the first base and collector. Good show as always!

Very clear, excellent demo. Cheers!

Good Video...

@jamest.5001 7 лет назад

great video. I wish you included examples of circuits that commonly use Darlington transistors. I am very interested. and would like to know more. like when to use a Darlington. or could a MOSFET be used. also why use a transistor over a MOSFET? I have so many questions. great video...

@bunch8 6 лет назад

Yes, I'd also like to see a video on when to use what. Good video as usual.

I think MOFFETs are used mainly for really high frequencies, where regular transistors can't switch fast enough.

@SerenoOunce 3 года назад

@@TortureBot MOSFET's are typically faster for switching a load whereas BJT's are faster for signals. So depends on the application.

If you take a look at the internals of an opamp, you'll see a _bunch_ of them.

Just curious in the test with one transistor the base current was 42uAmps and when you connected both into darlington the base current drop even though you said on tape it increased but actually on the meter it showed decrease to 6uAmps why would that change like that you used the same base resister?

@uditsaxena3844 3 года назад

Thanks sir 😍

@megaraitei 5 лет назад

Basically it only allows more current to pass through, for a considerable small base current. I don't think it can actually create current amperage over and above the max that can be drawn from the power source. Can it ?? What about voltage ??

@michaelpadovani9566 7 лет назад

Actually never heard of this - looking fwd to trying this out like you did when my transistors make it here from China. You said these are quite common - can you give a few examples where they're used? Radios perhaps?

Every diagram of an NPN transistor I have seen shows the collector on the left; the base in the middle; and the emitter on the right - when the flat side is facing me. However, in this video, the collector and emitter seem reversed! Is anyone else seeing the same thing? If not, if the flat side is facing me: from left to right, should it be emitter; base; collector?

@talideon 2 года назад

You can orient them whatever way you like. The only thing that matters is that the arrow points away from the gate towards the emitter of the NPN transistor. For a PNP, the arrow points at the gate from the emitter. The arrow is basically acting as an indicator of the flow of conventional current: with the NPN transistor, the current flows from the collector and gate to the emitter; with a PNP, it flows from the emitter to the gate and collector. The important thing is to keep in mind the implication of which side the arrow is on, which indicates the emitter pin, and its orientation, which indicates its type and current flow. The typical orientation I've usually seen is the one Paul used here, but it's not the only one.

The exceptional gain is probably a good excuse to buy one whose characteristics are already determined and save frying components if you have a wee faux pas!

+gartmorn yes indeed
