ACST310-8B

Overvoltage protected AC switch

Datasheet − production data

Description

287

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.

&20

This ACST310-8B 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.The component

'3$.

Features

needs a low gate current to be activated (I max.

•

AC switch with self over voltage protection

10 mA) and still shows a high electrical noise

immunity complying with IEC standards such as

IEC 61000-4-4 (fast transient burst test).

Microcontroller direct driven (low gate current

max. 10 mA)

•

Three quadrants (Q1, Q2 and Q3)

ECOPACK 2 compliant component

Benefits

•

Enables equipment to meet IEC61000-4-5

High immunity against fast transients

described in IEC61000-4-4 standard

•

Needs no external overvoltage protection

High off-state reliability power device

Interfaces directly with the microcontroller

Reduces component count
