The 2P4M SCR (Silicon Controlled Rectifier) is an electronic component composed of four layers arranged in a PNPN structure with three terminals. Primarily used for regulating AC current, it operates unidirectionally, permitting current flow in only one direction. Widely applied in power converters, regulators, rectifiers, and switching systems, these devices boast resilience against high currents and voltages. Click Silicon Controlled Rectifier  to learn more
