What is SCR? Important Types, Working & Applications

SCR stands for Silicon Controlled Rectifier. It is a type of semiconductor device that belongs to the family of thyristors, which are widely used in power electronics. An SCR is a four-layer, three-terminal device with three pn-junctions. The three terminals of an SCR are the anode (A), the cathode (K), and the gate (G).
