Features
Blocking voltage: VDRM / VRRM = +/- 700 V
Avalanche controlled: VCL typ. = 1100 V
Nominal conducting current: IT(RMS) = 2 A
Gate triggering current: IGT < 10 mA
High noise immunity: static dV/dt > 500 V/µs
Benefits
Needs no more external protection snubber or
varistor
Enables equipment to meet IEC 61000-4-5
Reduces component count up to 80%
Interfaces directly with the micro controller
Eliminates any gate kick back on the micro-
controller
Allows straightforward connection of several
AC switches on same cooling pad
Datasheet - production data
Applications
AC static switching in appliance control
systems
Drive of low power high inductive or resistive
loads like:
– Relay, valve, solenoid, dispenser
– Pump, fan, micro-motor
– Defrost heater
Description
The ACS120 belongs to the AC line switch family.
This high performance switch circuit is able to
control a load of up to 2 A.
The ACS™ switch embeds a high voltage
clamping 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.
