2 Application information
2.1 Typical application descriptions
The ACST1635-8FP device can be used to control medium power load, such as AC motors
in home appliances. Thanks to its thermal and turn off commutation performances, the
ACST1635-8FP switch is able to drive an inductive load up to 16 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.
