(AC Switch Family)
ACST8
OVER VOLTAGE PROTECTED
AC POWER SWITCH
MAIN APPLICATIONS
■ AC static switching in appliance & industrial
control systems
■ Washing machine with bi-rotational induction
motor drive
■ Induction motor drive for:
- refrigerator / freezer compressor
- air conditioning compressor
FEATURES
■ VDRM /VRRM = +/- 800V
■ Avalanche controlled device
■ IT(RMS) = 8A with TCASE = 90 °C
■ High noise immunity: static dV/dt > 750 V/µs
■ Gate triggering current : IGT < 30 mA
■ Snubberless turn off commutation:
(dI/dt)c > 4.5A/ms
BENEFITS
■ Enables equipment to meet EN61000-4-5
standard
■ High off-state reliability with planar technology
■ Need no external overvoltage protection
■ Reduces the power component count
DESCRIPTION
The ACST8-8C belongs to the AC power switch
family built around the ASDTM technology. This
high performance device is adapted to home appli-
ances or industrial systems and drives an induc-
tion motor up to 8A.
This ACST switch embeds a triac structure with a
high voltage clamping device to absorb the induc-
tive turn off energy and withstand line transients
such as those described in the IEC61000-4-5
standards.
