ACST4(2003) Datasheet - STMicroelectronics

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 = +/-700V
■ Avalanche controlled : VCL typ = 1100 V
■ Nominal conducting current : IT(RMS) = 4A
■ High surge current capability: 30A for 20ms full wave
■ Gate triggering current : IGT < 10 mA or 25mA
■ Switch integrated driver
■ High noise immunity : static dV/dt >500V/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 < 10mA)

MAIN APPLICATIONS
■ AC static switching in appliance control systems
■ Drive of low power high inductive or resistive loads like
    - spray pump in dishwashers
    - fan in air-conditioners
