... Application information 2.1 Typical application description The ACST2 device has been designed to switch on and off highly inductive or resistive loads such as pump, valve, fan, or bulb lamp. Thanks to its high sensitivity (I ACST2 can be driven directly by logic level circuits through a resistor as shown on the typical application diagram. Thanks to its thermal and turn-off commutation performances, the ACST2 switch can drive, without any additional snubber, an inductive load Figure 16. AC induction motor control – ...

... ACST2 2.2 AC line transient voltage ruggedness In comparison with standard Triacs, which are not robust against surge voltage, the ACST2 is self-protected against over-voltage, specified by the new parameter V ACST2 is a sensitive device (I fast transients. The ACST2 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 ...

... The ACST2 is a sensitive device (I simple resistor by a logic level circuit, and still provides a high electrical noise immunity. The intrinsic immunity of the ACST2 is shown by the specified dV/dt equal to 500 V/µs @ 125 °C. This immunity level times higher than the immunity provided by an equivalent standard technology Triac with the same sensitivity ...
