Description
The ACST1235-8FP belongs to the
ACS™ / ACST power switch family built with
A.S.D.
®
(application specific discrete) technology.
This high performance device is suited to home
appliances or industrial systems and drives loads
up to 12 A.
This ACST1235-8FP 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 standard. It offers an
extremely high static dV/dt immunity of 2 kV/μs
minimum at 150 °C junction temperature.
ACST1235-8FP enables applications to be
compliant with IEC 61000-4-4 and IEC 61000-4-5.
