AC LINE SWITCH BASIC APPLICATION
The ACS108 device is well adapted to washing machine, dishwasher, tumble drier, refrigerator, water
heater and cookware. It has been designed especially to switch ON and OFF low power loads such as so-
lenoid, valve, relay, micro-motor, fan, pump, door lock and low wattage lamp bulb.
Pin COM:
Pin G:
Common drive reference to connect to the power line neutral
Switch Gate input to connect to the digital controller
Switch Output to connect to the Load
Pin OUT:
The 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. Note that no
protection device (zener or capacitor) should be added between gates and common terminals.
The SOT223 version allows several ACS108 devices to be connected on the same cooling PCB pad which
is the COM pin : this cooling pad can be then reduced, and the printed circuit layout is simplified.
In appliances systems, the ACS108 switch intends to drive low power load in full cycle ON / OFF mode.
When the gate signal is removed, the load is switched off after a delay time that is equal to one half line cy-
cle or one full line cycle depending on the load drive strategy.
The turn off commutation characteristics of these loads can be classified in 3 groups as shown in table 1.
Thanks to its thermal and turn off commutation performances, the ACS108 switch is able to drive with no
additional turn off snubber, a resistive or inductive load up to 0.2 A (when this load has to switch off within
one half AC line cycle), an inductive load up to 0.6 A or a resistive load up to 0.8 A (when this load has to
switch off within one full AC line cycle).

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 through the avalanche
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 20 mJ and is dissipated in the clamping section that is especially designed for that
purpose.

AC LINE TRANSIENT VOLTAGE RUGGEDNESS
The ACS108 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 4 is representative of the final ACS application and is also used to stress the
ACS switch according to the IEC1000-4-5 standard conditions. Thanks to the load, the ACS switch
sustains 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 4. Such non repetitive test can be done 10
times on each AC line voltage polarity.

resistive and inductive loads according to IEC
1000-4-5 standard.
