Features

• Enables equipment to meet IEC 61000-4-5 surge with overvoltage crowbar

technology

• High noise immunity against static dV/dt and IEC 61000-4-4 burst

• Needs no external protection snubber or varistor

• Reduces component count by up to 80% and Interfaces directly with the microcontroller

• Common package tab connection supports connection of several alternating

current switches on the same cooling pad

• VCL gives headroom before clamping then crowbar action

Description

The ACS108-8SN belongs to the AC switch range (built with A. S. D.® technology).

This high performance switch can control a load of up to 0.8 A.

This device switch includes an overvoltage crowbar 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.

Applications

• Alternating current on/off static switching in appliances and industrial control

systems

• Driving low power high inductive or resistive loads like:

– relay, valve, solenoid, dispenser

– pump, fan, low power motor, door lock, air flow dumper

– lamp
