DESCRIPTION
The ACS120 belongs to the AC line switch family
built around the ASD™ concept. This high perfor-
mance switch circuit is able to control a load up to 2
A.
S
The ACS™ switch embeds a high voltage clamp-
ing structure to absorb the inductive turn off energy
and a gate level shifter driver to separate the digital
controller from the main switch. It is triggered with
a negative gate current flowing out of the gate pin.

AC LINE SWITCH BASIC APPLICATION
The ACS120 device is well adapted to Washing machine, dishwasher, tumble drier, refrigerator,
air-conditioning systems, and cookware. It has been designed especially to switch on & off low power loads
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.

HIGH INDUCTIVE SWITCH-OFF OPERATION
At the end of the last conduction half-cycle, the load current reaches the holding current level IH , 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 VCL.
The energy stored in the inductance of the load depends on the holding current IH and the inductance (up
to 10 H); it can reach about 10 mJ and is dissipated in the clamping diode section. The ACS switch sustains
the turn off energy because its clamping section is designed for that purpose.

AC LINE TRANSIENT VOLTAGE RUGGEDNESS
The ACS120 switch is able to sustain safely the AC line transient voltages either by clamping the low en-
ergy spikes or by breaking over under high energy shocks, even with high turn-on current rises.
The test circuit of the figure C is representative of the final ACS application and is also used to stress the
ACS switch according to the IEC 61000-4-5 standard conditions. Thanks to the load, the ACS switch sus-
tains the voltage spikes up to 2 kV above the peak line voltage. It will break over safely even on resistive
load where the turn on current rise is high as shown on figure D. Such non repetitive test can be done 10
times on each AC line voltage polarity.
