The ACS108 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. The ACS108 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. Figure 1. Functional diagram

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 micro-controller Common package tab connection supports connection of several alternating current switches on the same cooling pad VCL gives headroom before clamping then crowbar action
