ACST12
Overvoltage protected AC switch
Features
■ Triac with overvoltage crowbar technology
■ Low I
GT
(<10 mA) or high immunity
(I
GT
<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 such as:
– Universal motor of washing machine drum
– Compressor for fridge or air conditioner
Description
The ACST12 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 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 standard. The ACST1210-7 needs
a low gate current to be activated (I
GT
< 10 mA)
and still provides a high electrical noise immunity
complying with the IEC 61000-4-4 standard. The
ACST1235-7 offers an extremely high static dV/dt
immunity of 2 kV/µs minimum.
