– complies with UL standards

(file ref: E81734)

– insulation voltage: 2000 VRMS

Datasheet - production data

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 ACST6 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 6 A.

This ACST6 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 ACST610 needs

only 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).
