Silicon Controlled Rectifier & the Crowbar Circuit
 
In this video we take a look at the basics of the Silicon Controlled Rectifier, or SCR. There’s also a little history about the Shockley diode and its evolution into the four layer device with a gate terminal, better known as the SCR. Different methods of latching-on the device are covered, and methods to turn the device off. We build a little tabletop demonstration to show how to actually turn on and off.
This is also the second video in which I recorded my own music - so please give a thumbs up if you enjoyed it. Thanks for watching and please subscribe!
