Description

General part information

ACST310-8B Series

The ACST310-8B 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 3 A.

This ACST310-8B switch embeds a Triac structure with 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.The component needs a low gate current to be activated (IGT max. 10 mA) and still shows a high electrical noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test).
