The ACS120 device is well adapted to Washing machine, dishwasher, tumble drier, refrigerator,
air-conditioningsystems,andcookware.Ithasbeendesignedespeciallytoswitchon&offlowpowerloads
such as solenoid, valve, relay, dispenser, micro-motor, pump, fan and defrost heaters.
Pin COM: Common drive reference to connect to the power line neutral
Pin G: Switch Gate input to connect to the digital controller
Pin OUT: Switch Output to connect to the load
This ACS switch is triggered with a negative gate current flowing out of the gate pin G. It can be driven di-
rectly by the digital controller through a resistor as shown on the typical application diagram.
Thanks to its thermal and turn off commutation performances, the ACS120 switch is able to drive with no
turn off additional snubber an inductive load up to 2 A.

TYPICAL APPLICATION DIAGRAM
At the end of the last conduction half-cycle, the load current reaches the holding current level I
H
, and the
ACS switch turns off. Because of the inductance L of the load, the current flows then through the ava-
lanche diode D and decreases linearly to zero. During this time, the voltage across the switch is limited to
the clamping voltage V
CL
.
The energy stored in the inductance of the load depends on the holding current I
H
and the inductance (up
to10H);itcanreachabout10mJandisdissipatedintheclampingdiodesection.TheACSswitchsustains
the turn off energy because its clamping section is designed for that purpose.
