ASD™
AC Switch Family
ACST6-7S
OVER VOLTAGE PROTECTED
AC POWER SWITCH
MAIN APPLICATIONS
s AC static switching in appliance & industrial
control systems
s Induction motor drive actuator for:
- Refrigerator / Freezer compressor
- Dishwasher spray pump
- Clothes drier tumble
s Actuator for the thermostat of a refrigerator or
freezer
FEATURES
s VDRM / VRRM = +/- 700V
s Avalanche controlled device
s IT(RMS)=1.5 A with no heat sink and Tamb = 40°C
s IT(RMS) = 6A with TCASE = 105 °C
s High noise immunity: static dV/dt > 200 V/µs
s Gate triggering current : IGT < 10 mA
s Snubberless turn off commutation:
(dI/dt)c > 3.5A/ms
s D2PAK, I2PAK, TO-220FPAB or TO-220
package
BENEFITS
s Enables equipment to meet IEC61000-4-5
standards
s High off-state reliability with planar technology
s Needs no external overvoltage protection
s Direct interface with the microcontroller
s 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 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.
