application information acst1035 - 8fp 8 / 13 docid025321 rev 2 figure 18 : resistive load control C typical diagram 2.2 ac l ine transient voltage ruggedness in comparison with standard triac, which need additional protection components against surge voltage, this device is self - protected against overvoltage, specified by the new paramet er v cl . its switch can safely withstand ac line transient voltages either by clamping the low energy spikes, such as the inductive spikes at switchoff, 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 fig ure 20. the acst1035 - 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 10 times on each ac line voltage polarity.
