Thanks to its thermal and turn off commutation performances, the ACST1635-8FP switch is able to drive an inductive load up to 16 A with no turn off additional snubber. It also provides high thermal performances in static and transient modes such as the compressor inrush current or high torque operating conditions of an AC motor. Figure 15.

The ACST1635-8FP 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 represents the ACST1635-8FP 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 is limiting 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 ACST1635-8FP folds back safely to the on state as shown in . The ACST1635-8FP 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. Figure 18.
