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.

The ACS™ switch embeds a Triac structure with a high voltage clamping device to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC61000-4-5 standards.

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

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
