Application information
Typical application description
The ACST8 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 ACST8
switch is able to drive an inductive load up to 8 A with no turn off additional snubber. It also
provides high thermal performances in static and transient modes such as high torque
operating conditions or inrush current of an AC motor.
