Working principles of SCR

What is SCR?

A Silicon-Controlled Rectifier (SCR) is a four-layer (p-n-p-n) semiconductor device that doesn't allow current to flow until it is triggered and, once triggered, will only allow the flow of current in one direction. It has three terminals: 1) an input control terminal referred to as a 'gate'; 2) an output terminal known as the 'anode'; and 3) a terminal known as a 'cathode', which is common to both the gate and the anode.
