The BTW69-200 from STMicroelectronics is a Silicon Controlled Rectifier that is ideal for solid-state relays, welding equipment, high-power motor control, controlled AC/DC bridge, and heating systems applications. It has a break-over voltage of 1200 V and a break-over current of 50 A. This rectifier has a gate trigger voltage of 1.3 V and a gate trigger current of less than 80 mA. It is suitable for applications where power handling and dissipation are critical and offers excellent performance in terms of surge current handling capability, allowing usage in industrial environments.

This silicon-controlled rectifier consists of a ceramic pad that provides high voltage 2500 V (RMS) insulation, which complies with the UL standards. It is available in a through-hole package that measures 15.10 x 4.40 mm.
