ACS108

ACS108 Overvoltage protected AC switch (ACS™) Datasheet - production data Description COM COM OUT G G COM OUT TO-92 ACS108-6SA ACS108-8SA SOT-223 ACS108-6SN ACS108-8SN 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 OUT 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 G COM OUT G COM Common drive reference to connect to the mains Output to connect to the load. Gate input to connect to the controller through gate resistor Table 1.
