FEATURES

The ACST4 belongs to the AC power switch family

built around the ASD™ technology. This high per-

formance device is adapted to home appliances or

inductrial systems and drives loads up to 4 A.

The ACS™ switch embeds a Triac structure with a

high voltage clamping device to absorb the induc-

tive turn-off energy and withstand line transients

such as those described in the IEC61000-4-5 stan-

dards.
