2.1.2 AC line transient voltage ruggedness

The ACS108-6S switch is able to withstand safely the AC line transients 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 shown in Figure 16 is representative of the final ACS108-6S application, and is

also used to test the ACS switch according to the IEC 61000-4-5 standard conditions. Thanks

to the load limiting the current, the ACS108-6S switch withstands the voltage spikes up to 2 kV

above the peak line voltage. The protection is based on an overvoltage crowbar technology.

Actually, the ACS108-6S breaks over safely as shown in Figure 17. The ACS108-6S recovers

its blocking voltage capability after the surge (switch off back at the next zero crossing of the

current).

Such non-repetitive tests can be done 10 times on each AC line voltage polarity.
