ACST12

Transient protected AC power switch

Features

■ Triac with overvoltage crowbar technology

■ Low IGT (<10 mA) or high immunity

(IGT<35 mA) version

■ High noise immunity: static dV/dt > 2000 V/µs

Benefits

■ Enables equipment to meet IEC 61000-4-5

■ High off-state reliability with planar technology

■ Need no external over voltage 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 like:

– Universal drum motor of washing machine

– Compressor for fridge or air conditioner

Description

The ACST12 series belongs to the ACS/ACST

family built with the ASD (application specific

discrete) technology. This high performance

device is adapted to home appliances or industrial

systems and drives loads up to 12 A.

This ACST12 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 ACST12-7S needs a

low gate current to be activated (IGT < 10 mA) and

in the mean time provides a high electrical noise

immunity such as those described in the IEC

61000-4-4 standards. The ACST12-7C offers an

extremely high static dV/dt immunity of 2 kV/µs

minimum.
