ACST8

Overvoltage protected AC switch

Features

■ Triac with overvoltage protection

■ High noise immunity: static dV/dt > 2000 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 ACST8 series belongs to the ACS™/ ACST

power switch family built around A.S.D.®

(application specific discrete) technology. This

high performance device is suited to home

appliances or industrial systems and drives an

induction motor up to 8 A.

This ACST8 device 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.

ACST8 shows a high noise immunity complying

with IEC standards such as IEC 61000-4-4 (fast

transient burst test).
