Needs no external overvoltage protection.
Enables the equipment to meet IEC61000-4-5
standard.
Allows straightforward connection of several
SOT-223 devices on the same cooling pad.
Reduces the switch component count by up to
80%.
Interfaces directly with the microcontroller.
Eliminates any stressing gate kick back on the
microcontroller.

DESCRIPTION
The ACS108 belongs to the AC line switches built
around the ASD鈩?concept. This high performance
device is able to control an 0.8 A load device.
The ACS鈩?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.
