THE DARLINGTON PAIR EXPLAINED: Putting two PN junction transistors back to back.

[@johnmcgiv1]

Hi I am just an old guy trying to pick up some electronic knowledge this was inspiring for me I would like to say a big thank you the way you explained how to breakdown the circuit and arrive at the values is priceless, many thanks.

EE here. hFE is an abbreviated term for "Hybrid parameter forward current gain, common emitter". I believe the abbreviation came about when it was used on multimeters. A kind of crude short hand for the test of current gain in a common emitter configuration.

[@TheElectricAcademy]

Ahhh. That makes sense.

[@Soho9111]

thank you for simplifying it like that,

[@maxwarfield6699]

This is a great video, for a complete NOOB like me - thank you. You've explained everything clearly and at a normal speaking-speed [I feel that most electronic tutorials online, are narrated by bored ex-electricians-or-electrical-engineers who sound like they are in a RUSH to catch a bus or something - speeding through some gnarly techno-jargon that only other electricians and/or electrical-engineers would/could understand - which defeats the purpose of a TUTORIAL, which is meant for those of US, who want to LEARN. NOT those who already know.]. Please make more videos, I'm learning a lot. I've pressed the LIKE button and I've subscribed to your channel. Thanks again. Stay safe. Cheers!

Thank you so much! You just made everything look so easy ! Who the hell? I so much love you and your beautiful 😍 mind.

[@willem-debeer]

Brilliantly well explained... finally got it, thanks.

[@claytonbenignus4688]

I can’t wait to see your take on the Sziklai Pair.

[@danielvanachterbergh8103]

Do you have the link for that worksheet?

[@PhG1961]

Excellent video and very well explained. Also quite entertaining !

[@TheElectricAcademy]

Glad you enjoyed it! I have a lot of fun making them.

[@PhG1961]

@@TheElectricAcademy I'm watching the other videos right now. Keep making them !! It's fun and for me it's excellent for freshing up my dusty memory. It's all coming back now... ;-)

[@santiagotutor2008]

That must be a 10 ohm resistor then. You noted it at the end. Great Video

[@jacquescornwell2610]

Hi Chad would I be able to get the link to the worksheet? Thank you

[@random_Person347]

Great content and good presentation, but the background "music" is irritating. Glad it's not louder.

[@onlyhumblehuman]

Great video. Easy to understand even for me from Croatia and I am not so god in english!

[@chichileno]

Great video. It will help me a lot with my final exams... BTW, there's no link to the worksheet you mention in minute 3:00, is it possible that you put the link?

[@ckmNtA]

Awesome Video Thanks. Question Please : Can you run more than one pair of transistors? Maybe Triple or Quad (eg : Darlington Quad?) or more and if so would that be exponential current gains? Or can you only parallel Darlington pairs to reach your required amperage?

[@josephguida5432]

I can’t see why not but you will have the disadvantage of the voltage drop multiplied by the number of Vbe’s and that 3rd transistor would need to dissipate so much heat. That’s just my 2 cents and I’ll admit I have no experience improvising transistor circuits IRL but I have years of experience troubleshooting industrial logic circuits and the positive logic sensor/switches were at most a Darlington with other passive elements. The way I see it, the third device downstream might as well be an ice cube relay with a fly back diode across the coil contacts or the input terminal of a PLC.

[@holdenlaw9964]

Good video, thank you

[@holdenlaw9964]

Can you teach me how to find Vce of the Q1? 🤔

[@willem-debeer]

HFE... just a thought... High Frequency Emitter? :/

[@tortoisehead30]

Could you do similar videos for other ways to bias transistors?

[@terrybutler6665]

High frequency electrode

[@donkingarago4143]

wheres the sheets?

[@benseal5820]

The only thing I don't understand is the 100 K ohms and the 10 K ohms/10 ohms. From my knowledge electricity is lazy and whats stopping all of it goingstright to RC. If you have another video, I'll keep watching your videos but if you or someone could explain I'll be grateful.

[@TheElectricAcademy]

Don’t even get me started on those!!!!! Just kidding. I had to look up what those were. Lol

[@patsylandri2066]

Can you send me a work sheet? thanks

[@spencerw682]

Hybrid Foreward Emitter

[@h7opolo]

tone is too abrasive and cadence too staccato for me to pay attention.
