STMICROELECTRONICS Triac AC Switch 600V 800mA SOT-223

The STMICROELECTRONICS Overvoltage Protected AC Switch is a high-performance triac designed for 0.8A, 600V applications. Featuring an ACS™ architecture, this device incorporates a common package tab connection, which conveniently supports the connection of several alternating current switches on the same cooling pad, simplifying PCB layout and thermal management.

One of the standout features of this triac is its overvoltage crowbar technology, which enables equipment to meet the IEC 61000-4-5 surge standard. It also provides high noise immunity against static dV/dt and IEC 61000-4-4 burst events. The component needs no external protection snubber or varistor, significantly reducing the overall component count by up to 80%. Additionally, it interfaces directly with the microcontroller for straightforward integration, while the VCL feature gives headroom before clamping and activates the crowbar action for robust circuit protection.

This surface-mount switch is highly suitable for alternating current on/off static switching in both appliances and industrial control systems. It is specifically designed for driving low power, high inductive or resistive loads with reliability and efficiency.
