A Solid-state current controlling device divided into four layers is called a Silicon-controlled rectifier (SCR) or semiconductor controlled rectifier. Silicon-controlled rectifier is a unidirectional power switch used in switching between alternative current (AC) and direct current (DC). It is mainly used for rectifying DC signals in controlled AC output and vice versa.
