Transistor Relays

Transistor Relays

Transistor Relays: These are the most widely accepted type of static relays, so much so that when we say static relays, we can safely infer transistor relays only. The transistor…

Phototransistor Working

Phototransistor Working: A Phototransistor Working is similar to an ordinary BJT except that its collector base junction is constructed like a photodiode. Instead of a base current, the input to…

Programmable Unijunction Transistor

Programmable Unijunction Transistor: PUT Operation - The Programmable Unijunction Transistor (PUT) is actually an SCR-type device used to simulate a UJT. The interbase resistance (RBB) and the intrinsic standoff ratio…
