ACST4 Series
4/9
The ACST4 device has been designed to switch on & off low power, but highly inductive or resistive loads
such as dishwashers spray pumps, and air-conditioners fan.
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
ACST4-7S triggering current has to be sunk from the gate pin G. The switch can then be driven directly by
logic level circuits through a resistor as shown on the typical application diagram ( Fig A ).
Thanks to its thermal and turn off commutation performances, the ACST4 switch is able to drive with no
turn off additional snubber an inductive load up to 4 A.

TYPICAL APPLICATION DIAGRAM
(Fig. A)
The ACST4 switch is able to sustain safely the AC line transient voltages either by clamping the low energy
spikes or by breaking over under high energy shocks, even with high turn-on current rises.
The test circuit of the figure 2 is representative of the final ACST application and is also used to stress the
ACST switch according to the IEC 61000-4-5 standard conditions. Thanks to the load, the ACST switch

load where the turn on current rate of rise, is as high as shown on figure 3. Such non-repetitive test can be
done 10 times on each AC line voltage polarity.
