Application information ACST10

2 Application information
2.1 Typical application description
The ACST10 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
ACST10 switch is able to drive an inductive load up to 10 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 ACST1010-7 can be driven directly by an MCU
through a simple gate resistor as shown Figure 15.
