STMICROELECTRONICS ACST2108BTR AC Switch
The ACST2 series is a high-performance, overvoltage protected AC switch suitable for industrial and home applications. It features a Triac with crowbar technology, enabling reliable switching of loads up to 2 A, and offers high noise immunity with static dV/dt > 500 V/us. The device's insulated TO-220FPAB package complies with UL standards, with an insulation voltage of 2000 VRMS. Designed for environments with line transients, it provides robust overvoltage clamping, eliminates external protection needs, and can directly interface with microcontrollers for AC on/off switching of resistive or inductive loads like motors and pumps.
