Electrical noise immunity

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
