(Application Specific Devices)

ACST6

OVER VOLTAGE PROTECTED

AC POWER SWITCH

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

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

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

DESCRIPTION

The ACST6-7Sx belongs to the AC power switch

family built around the ASD technology. This high

performance device is adapted to home appli-

ances or industrial systems and drives an induc-

tion 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.
