Application information
Typical application description
The ACST4 device has been designed to control medium power load, such as AC motors in
home appliances. Thanks to its thermal and turn off commutation performances, the ACST4
switch is able to drive an inductive load up to 4 A with no turn off additional snubber. It also
provides high thermal performances in static and transient modes such as the compressor
inrush current or high torque operating conditions of an AC motor. Thanks to its low gate
triggering current level, the ACST4 can be driven directly by an MCU through a simple gate
resistor as shown
