Application information
Typical application description
The ACST12 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
ACST12 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. Thanks
to its low gate triggering current level, the ACST1210-7 can be driven directly by a MCU
through a simple gate resistor as shown in
