DESCRIPTION
The ACST4 belongs to the AC power switch family
built around the ASD™ technology. This high performance 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 inductive turn-off energy and withstand line transients
suchasthosedescribedinthe IEC61000-4-5 standards.
