KP20A600V is 20A, Phase Control Thyristor.

A Phase Control Thyristor, also known as a Silicon-Controlled Rectifier (SCR), is a type of semiconductor device used in power electronics for controlling high-power loads by conducting current in only one direction. It is a four-layer, three-junction semiconductor device with three terminals: an anode, a cathode, and a gate.

The basic operation of a phase control thyristor involves controlling the time at which it starts to conduct current during each AC half-cycle. This allows the thyristor to control the power delivered to the load and is commonly used for applications that require varying the output voltage or current to control the speed of motors, regulate power to heaters, and dim lights in lighting circuits.
