Learn what Darlington transistors are and why they have such a large current gain (beta value). See why Darlington transistors are sometimes used as switches instead of regular BJTs.

Fantastic explaination, especially the practical example at the end!
Excellent explanation sir. Super ????. Please upload more videos on electronics sir
Hi, I have 5V 100mA in my circuit/power supply and I have a load of 250mA can I use a Darlington to boost/amplify the current so that it can drive the load?
Why would you choose to use a carefully designed linear component as a digital switch? There are dozens of components designed for the purpose. Good design is about proper selection not force fits.
Hi good day, excellent videos and how to explain I wanted you to help me with a doubt HOW DO I MAKE A Darlington BUB941ZT WITH TWO CONVENTIONAL TRANSISTORS? WHAT do I have to take into account when combining them, can they be different or do they have to be the same?
THE VOLTAGE THE CURRENT AND THE Hfe The darlntong that I need your data are
Vceo 350 VOLTS
Hfe 300
Ic 15 A
POWER 150 watts
HELLO THERE . THERES A TIP142 NPN TRANSISTOR IM TRYING TO USE IN MY ONE TRANSISTOR SOUND AMP . SO TELL ME WHERE IS THE EXIT IS IT AN EMITTER OR COLLECTOR ???
oh churchie boys
Good video! Darlington Transistors can't' go into saturation though; the base emitter voltage would be higher than the collector emitter voltage of the large current transistor.
Sir you are using transistor in saturation and using relation Ic=beta.Ib
But I have heard that above relation is true only when operated in active region then how are you using that relation in saturation??
what if 1000 transistors arranged like Darlington ? what if infinitely many ?
If I had a voltage on the emitter side, like for example in a switching power converter circuit, how does one go about selecting an appropriate Rb? Because wouldn't the voltage be 3.3 – 1.4 – Ve, making it negative if Ve was large enough.
why did you multiply Ic(sat) by 5 in the second part of the video? Isn't it just Ib= Ic(sat)/B
Fantastic video, thank you!
Where can I find the value of Curent Saturation for my transistor?
A good explanation on the Darlington's, thank you for this video. As old as I am I'm starting to learn electronics all over from where I dropped off from them in the late 70's, so videos such as these are very helpful to the people who really want to learn these electronics of today, which has changed a lot since the 70's so once again thanks for a great explanation.
Where can I find the value of beta for my transistor?
Great Video . Great explanation Than you so much!!!
great video
Well explained. Thanks. Also… FIRST!
