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.

Silicon-controlled rectifiers have multitude of applications including motor controls, pressure control regulators, light dimmers, liquid level regulators and electronic automotive ignition. From end use perspective, applications of SCR are found in industries such as semiconductor and consumer electronics, power transmission, clean energy, aerospace and defense, automotive, medical and oil and gas among others. Rise in applications of SCR in these industries is driving the growth of the market across different countries in the world.
