8 AC line transient voltage ruggedness 2.2 AC line transient voltage ruggedness In comparison with standard riacs, which needs additional protection components against surge voltage, the ACS1635-8FP is self-protected against overvoltage, specified by the new parameter CL. he ACS1635-8FP switch can safely withstand AC line transient voltages either by clamping the low energy spikes, such as the inductive spikes at switch off, or by switching to the on state (for less than 1 ms) to dissipate higher energy shocks through the load. his safety feature works even with high turn-on current ramp-up. he test circuit of represents the ACS1635-8FP application, and is used to stress the ACS switch according to the IEC standard conditions. With the additional effect of the load which is limiting the current, the ACS switch withstands the voltage spikes up to 2 k on top of the peak line voltage. he protection is based on an overvoltage crowbar technology. he ACS1635-8FP folds back safely to the on state as shown in. he ACS1635-8FP recovers its blocking voltage capability after the surge and the next zero crossing current. Such a non repetitive test can be done at least 1 times on each AC line voltage polarity. Figure 18.
