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

ACST12-7CT属于分立半导体产品 > 晶闸管 - TRIAC。意法半导体（ST）集团制造生产的ACST12-7CT晶闸管 - TRIAC晶闸管可沿一个方向或在半个 AC 周期内传导 AC（交流电）。当 TRIAC（三极管 AC）的门极被触发时，即会沿任一方向传导电流。其他名称包括双向三极晶闸管或双侧三极晶闸管。TRIAC 分为无缓冲器、Alternistor、内部触发、逻辑门和标准型，安装方式包括底座、表面或通孔安装。这些器件可根据断态电压、通态电流、保持电流和门极触发电压进行选择。
