Description

The ACST4 belongs to the AC power switch family built around the ASD™ technology. This high performance device is adapted to home appliances or inductrial systems and drives loads up to 4 A.

Features

■ Blocking voltage: VDRM /VRRM = ±700 V

■ Avalanche controlled: VCL typ = 1100 V

■ Nominal conducting current : IT(RMS) = 4 A

■ High surge current capability: 30 A for 20 ms full wave

■ Gate triggering current: IGT < 10 mA or 25 mA

■ Switch integrated driver

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

Benefits

■ Enables equipment to meet IEC 61000-4-5

■ High off-state reliability with planar technology

■ No external overvoltage protection needed

■ Reduces the power component factor

■ Interfaces directly with the microcontroller

■ Direct interface with the microcontroller for the ACST4-7S (IGT

Main applications

■ AC static switching in appliance control systems

■ Drive of low power high inductive or resistive loads like

– spray pump in dishwashers

– an in air-conditioners

ACST435-8BTR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ACST435-8BTR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。
