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, with no turn off additional snubber, an inductive load up to
12 A. 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 ACST12-7S can be driven directly by a MCU through a
simple gate resistor as shown in
