Main features

The ACST2-8SFP in the TO-220FPAB package

Main application

industrial control systems

– solenoid,

– pump, fan, micro-motor

Description

The ACST2 series 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 loads

up to 2 A.

This ACST2 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

IEC 61000-4-5 standards. The component needs

and in the mean time provides a high electrical

noise immunity such as those described in the

IEC 61000-4-4 standards.
