SKET400-18ESemikron

SKET400-18E Description

SKET400-18E is a type of silicon-controlled rectifier (SCR), also known as a thyristor. SCRs are a type of semiconductor device that are used to control and switch high power electrical signals in a variety of industrial applications. The SKET400-18E is a high-voltage SCR with a maximum voltage rating of 1800 volts and a maximum current rating of 400 amps. It is designed for use in high power applications such as motor controls, power supplies, and welding equipment. The SCR is housed in a TO-200AB package, which provides a high level of thermal conductivity and allows for easy mounting on a heatsink for thermal management. It also features a gate trigger current of 200 mA, which allows for precise control of the device.
