Thyristor or silicon controlled rectifier is a multilayer semiconductor device and is similar to the transistor. Silicon controlled rectifier consists of three terminals (anode, cathode, and gate) unlike the two terminal diode (anode and cathode) rectifier.he silicon controlled rectifier or thyristor is represented by the symbol as shown in the figure. Silicon Controlled Rectifier. Silicon controlled rectifier is also a unidirectional device as it conducts only in one direction.
