ST300C datasheet



The ST300C is 560A, Phase Control Thyristor, SCR.

A Silicon Controlled Rectifier (SCR) is a type of semiconductor device that is widely used as a switch or rectifier in power control and voltage regulation circuits. It is a three-layer, four-terminal device that can control the flow of current in either direction and provide full-wave rectification in power conversion applications.

SCRs are widely used in power control and regulation applications, such as lighting and heating control, motor control, battery chargers, and AC-to-DC power conversion, due to their high voltage and current handling capabilities, fast switching speeds, and high reliability.
