Description

DESCRIPTION
The ACST6-7Sx belongs to the AC power switch family built around the ASD technology. This high performance device is adapted to home appliances or industrial systems and drives an induction motor up to 6A.
This ACST 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
■ VDRM /VRRM = +/- 700V
■ Avalanche controlled device
■ IT(RMS) = 1.5 A with no heat sink and Tamb = 40 °C
■ IT(RMS) = 6A with Tcase = 105 °C
■ High noise immunity: static dV/dt > 200 V/µs
■ Gate triggering current : IGT < 10 mA
■ Snubberless turn off commutation: (dI/dt)c > 3.5A/ms
■ D2PAK, I2PAK, TO-220FPAB or TO-220AB package

MAIN APPLICATIONS
■ AC static switching in appliance & industrial control systems
■ Induction motor drive actuator for:
   - Refrigerator / Freezer compressor
   - Dishwasher spray pump
   - Clothes drier tumble
■ Actuator for the thermostat of a refrigerator or COM COM freezer

BENEFITS
■ Enables equipment to meet IEC61000-4-5 standards
■ High off-state reliability with planar technology
■ Needs no external overvoltage protection
■ Direct interface with the microcontroller
■ Reduces the power component count
