ACS108-6S
AC switch family
Transient voltage protected AC Switch (ACS™)
Main product characteristics
IT(RMS)
VDRM/VRRM
IGT
0.8 A
600 V
10 mA
■ Overvoltage protection by crowbar technology
■ High noise immunity - static dV/dt > 500 V/µs
Applications
■ AC ON/OFF static switching in appliances and
industrial control systems
■ Drive of low power high inductive or resistive
loads like:
– relay, valve, solenoid,
– dispenser, door lock
– pump, fan, micro-motor
Benefits
■ Needs no external protection snubber or
varistor.
■ Enables equipment to meet IEC 61000-4-5.
■ Reduces component count by up to 80%.
■ Interfaces directly with the micro-controller.
■ Common package tab connection supports
connection of several alternating current
switches (ACS) on the same cooling pad.
■ Integrated structure based on ASD(a)
technology

Description
The ACS108-6S belongs to the AC line switch
family. This high performance switch can control a
load of up to 0.8A.
The ACS108-6S switch includes an overvoltage
crowbar structure to absorb the overvoltage
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.
