Description

The ACST1235-8FP belongs to the

ACS™ / ACST power switch family built with

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.
