ASD™
AC Switch Family
ACS120-7SB/SFP/ST
AC LINE SWITCH
MAIN APPLICATIONS
s AC static switching in appliance control systems
s Drive of low power high inductive or resistive
loads like
- relay, valve, solenoid, dispenser
- pump, fan, micro-motor
- defrost heater
FEATURES
s Blocking voltage : VDRM / VRRM = +/-700V
s Avalanche controlled : VCL typ = 1100 V
s Nominal conducting current : IT(RMS) = 2A
s Gate triggering current : IGT < 10 mA
s Switch integrated driver
s High noise immunity : static dV/dt >500V/µs
BENEFITS
s Needs no more external protection snubber or
varistor
s Enables equipment to meet IEC 61000-4-5
s Reduces component count up to 80 %
s Interfaces directly with the microcontroller
s Eliminates any gate kick back on the
microcontroller
s Allows straightforward connection of several
ACS™ on same cooling pad.
DESCRIPTION
The ACS120 belongs to the AC line switch family
built around the ASD™ concept. This high perfor-
mance switch circuit is able to control a load up to 2
A.
The ACS™ switch embeds a high voltage clamp-
ing structure to absorb the inductive turn off energy
and a gate level shifter driver to separate the digital
controller from the main switch. It is triggered with
a negative gate current flowing out of the gate pin.
