DESCRIPTION
The ACST4 belongs to the AC power switch family
built around the ASD鈩?technology. This high per-
formance device is adapted to home appliances or
inductrial systems and drives loads up to 4 A.
The ACS鈩?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.
