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. 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 (IGT < 10 mA)
and still shows a high electrical noise immunity
complying with IEC standards such as
IEC 61000-4-4 (fast transient burst test).
