The STMicroelectronics X0202NUF is a sensitive SCR (silicon-controlled rectifier) featuring a maximum current rating of 1.25 amperes (A) and a low gate current of 200 microamperes (uA). It is designed to provide fast and accurate triggering of control circuits with minimal power dissipation. It is suitable for applications such as UPS, solar inverter, static switch, AC/DC power converters, ballast, soft starters, motor control, and other industrial applications. Compared to traditional SCRs, the X0202NUF offers improved performance, with a higher current carrying capability, lower power loss, and enhanced reliability.
