Typical application description

The ACST1235-8FP 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 ACST1235-8FP switch is able to drive an inductive load up to 12 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.
