Description
The ACST6 series belongs to the ACS™/ACST
®
power switch family built with A.S.D. (application
G
specific discrete) technology. This high
performance device is suited to home appliances
or industrial systems, and drives loads up to 6 A.
COM
This ACST6 switch embeds a Triac structure and
a high voltage clamping device able to absorb the
inductive turn-off energy and withstand line
transients such as those described in the
IEC 61000-4-5 standards. The ACST610 needs
only low gate current to be activated
