... Typical application description The ACST8 device has been designed to control medium power load, such as AC motors in home appliances. Thanks to its thermal and turn off commutation performances, the ACST8 switch is able to drive an inductive load with no turn off additional snubber. It also provides high thermal performances in static and transient modes such as high torque operating conditions or inrush current motor ...

... ACST8 2.2 AC line transient voltage ruggedness In comparison with standard Triacs, which are not robust against surge voltage, the ACST8 is self-protected against over-voltage, specified by the new parameter V switch can safely withstand AC line transient voltages either by clamping the low energy spikes, such as inductive spikes at switch off switching to the on state (for less than 10 ms) to dissipate higher energy shocks through the load ...
