1 / 13 page  July 2007 Rev 4 1/13 ACST4 AC power switch 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 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 (I GT < 10 mA) 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 IEC 61000-4-5 standards.
