application information ACST1035-8FP 8/13 docid025321 rev 1 2.2 ac line transient voltage ruggedness in comparison with standard triac, which need additional protection components against surge voltage, the ACST1035-8FP is self-protected against overvoltage, specified by the new parameter v cl . the ACST1035-8FP 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 10 ms) to dissipate higher energy shocks through the load. this safety feature works even with high turn-on current ramp-up. the test circuit of figure 19 represents the ACST1035-8FP application, and is used to stress the acst switch according to the iec 61000-4-5 standard conditions. with the additional effect of the load which limits the current, the acst switch withstands the voltage spikes up to 2 kv on top of the peak line voltage. the protection is based on an overvoltage crowbar technology. the ACST1035-8FP folds back safely to the on state as shown in figure 20 . the ACST1035-8FP recovers its blocki ng voltage capability after the surge and the next zero crossing current. such a non repetitive test can be done at least 10 times on each ac line voltage polarity. figure 19. overvoltage ruggedness test circuit for resistive and inductive loads for iec 61000-4-5 standards ac mains filtering unit model of the load acst 2 kv surge r = 11 l = 3 h v = 2 kv , , pp rg = 62 rg r l rgene
