ACST2分立半导体产品的晶闸管-TRIAC规格书PDF中文资料

ACST2属于分立半导体产品的晶闸管-TRIAC。由意法半导体集团制造生产的ACST2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。

描述 Description

The ACST2 series belongs to the AC power switch family built around the ASD technology. This high performance device is adapted to home appliances or industrial systems and drives loads up to 2 A.

Main features

■ Overvoltage crowbar technology

■ High noise immunity: static dV/dt > 500 V/µs

The ACST2-8SFP in the TO-220FPAB package provides insulation voltage rated at 1500VRMS

Main application

■ AC ON/OFF static switching in appliances & industrial control systems

■ Drive of low power highlyresistive or inductive loads like:

– solenoid,

– pump, fan, micro-motor

Benefits

■ Enables equipment to meet IEC 61000-4-5

■ High off-state reliability with planar technology

■ Needs no external overvoltage protection

■ Reduces component count

■ Interfaces directly with the micro-controller

■ High immunity against fast transients described in IEC 61000-4-4 standards
