Description
The ACST12 series belongs to the ACS/ACST family built with the ASD (application specific discrete) technology. This high performance device is adapted to home appliances or industrial systems and drives loads up to 12 A.

Features
■ Triac with overvoltage crowbar technology
■ Low IGT (<10 mA) or high immunity (IGT<35 mA) version
■ High noise immunity: static dV/dt > 2000 V/µs

Benefits
■ Enables equipment to meet IEC 61000-4-5
■ High off-state reliability with planar technology
■ Need no external over voltage protection
■ Reduces the power passive component count
■ High immunity against fast transients described in IEC 61000-4-4 standards

Applications
■ AC mains static switching in appliance and industrial control systems
■ Drive of medium power AC loads like:
    – Universal drum motor of washing machine
    – Compressor for fridge or air conditioner
