ACS402-5SB4
4/8
Each ACS402 switch is able to safely withstand the AC line transient voltages either by clamping the low
energy spikes or by breaking over under high energy shocks.
The test circuit in Figure 3 is representative of the final ACS application and is also used to stress the
ACS switch according to the IEC61000-4-5 standard conditions. Thanks to the load, the ACS switch
withstands the voltage spikes up to 2 kV above the peak line voltage. It will break over safely even on resis-
tive load where the turn-on current rise is high as shown in Figure 4. Such non repetitive test can be done
10 times on each AC line voltage polarity.

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 through the avalanche
diode D and decreases linearly to zero. During this time, the voltage across the switch is limited to the
clamping voltage V
