ACST4

Overvoltage protected AC switch

Features

■ Triac with overvoltage protection

■ Low IGT (<10 mA) or high immunity

(IGT<35 mA) version

■ High noise immunity: static dV/dt > 1000 V/µs

■ TO-220FPAB insulated package: 1500 V rms

Benefits

■ Enables equipment to meet IEC 61000-4-5

■ High off-state reliability with planar technology

■ Needs no external overvoltage protection

■ Reduces the power passive component count

■ High immunity against fast transients

described in IEC 61000-4-4 standards

Applications

■ AC mains static switching in appliance and

industrial control systems

■ Drive of medium power AC loads such as:

– Universal motor of washing machine drum

– Compressor for fridge or air conditioner

Description

The ACST4 series 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 4 A.

This ACST4 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 standards. The ACST410 needs

only a low gate current to be activated (IGT < 10

mA) and still shows a high noise immunity

complying with IEC standards such as

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