ACST2
Overvoltage protected AC switch
Features
■ Triac with overvoltage crowbar technology
■ High noise immunity: static dV/dt > 500 V/µs
■ ACST210-8FP, in the TO-220FPAB package,
provides insulation voltage rated at 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 component count
■ Interfaces directly with the micro-controller
■ High immunity against fast transients
described in IEC 61000-4-4 standards
Applications
■ AC on/off static switching in appliances and
industrial control systems
■ Driving low power highly inductive loads like
solenoid, pump, fan, and micro-motor
Description
The ACST2 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 2 A.
This ACST2 switch 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. The component needs
a low gate current to be activated (I
GT
< 10 mA)
and still shows a high electrical noise immunity
complying with IEC standards such as
IEC 61000-4-4 (fast transient burst test).
