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 < 10 mA)

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
