Marking

BENEFITS Enables equipment to meet IEC61000-4-5 standards High off-state reliability with planar technology Needs no external overvoltage protection Direct interface with the microcontroller Reduces the power component count DESCRIPTION The ACST6-7Sx belongs to the AC power switch family built around the ASD technology. This high performance device is adapted to home appliances or industrial systems and drives an induction motor up to 6A. This ACST switch embeds a triac structure with a high voltage clamping device to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC61000-4-5 standards.
