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).
