Electrical noise immunity

Even if the ACST2 is a sensitive device (IGT = 10 mA) and can be controlled directly though

a simple resistor by a logic level circuit, it 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 is 5 to 10 times higher than the immunity provided by an equivalent

standard technology triac with the same sensitivity. In other word, ACST2 is sensitive, but

has an immunity reaching the one provided by non-sensitive device (IGT higher than 35 mA).
