ASD™
AC Switch Family
MAIN APPLICATIONS
s AC on-off static switching in appliance &
industrial control systems
s Drive of low power high inductive or resistive
loads like
- relay, valve, solenoid, dispenser
- pump, fan, micro-motor
- low power lamp bulb, door lock
FEATURES
s Blocking voltage : VDRM / VRRM = 500V
s Clamping voltage : VCL = 600 V
s Nominal current : IT(RMS) = 0.2 A
s Gate triggering current : IGT < 5 mA
s Switch integrated driver
s Triggering current is sourced by the gate
s SO-8 package:
- drive reference COM connected to 2 cooling pins
- 3.5 mm creepage distance from pin OUT to other
pins
BENEFITS
s Needs no external overvoltage protection
s Enables equipment to meet IEC61000-4-5 &
IEC 335-1
s Reduces component count by up to 80 %
s Interfaces directly with a microcontroller
s Eliminates any stressing gate kick back on
microcontroller
s Allows straightforward connection of several
ACS™ on same cooling pad.
DESCRIPTION
The ACS102 belongs to the AC line switch family
built around the ASD™ concept. This high perfor-
mance device is able to control an up to 0.3 A load
device.
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.
For further technical information, please refer to
AN1172 application note.
