Overview
The X0202NUF is a 1.25 A sensitive gate Silicon Controlled Rectifier (SCR) produced by STMicroelectronics. This device is designed to serve as an on/off function in applications where the topology does not provide high current for gate triggering. It is optimized for reduced power losses and high reliability in harsh environments, featuring low forward voltage drop and inrush current capabilities.
