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

– 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 microcontroller

– Allows straightforward connection of

several AC switches on same cooling pad

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.
