ACS108-8SA Datasheet 0.8 A - 800 V overvoltage protected AC switch (ACS) 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- COM controller G OUT Common package tab connection supports connection of several alternating current switches on the same cooling pad TO-92 V gives headroom before clamping then crowbar action CL OUT Applications Alternating current on/off static switching in appliances and industrial control systems G Driving low power high inductive or resistive loads like: relay, valve, solenoid, dispenser pump, fan, low power motor, door lock, air flow dumper COM COM Common drive reference to connect lamp to the mains OUT Output to connect to the load. G Gate input to connect to the controller through gate resistor Description The ACS108-8SA belongs to the AC switch range (built with A. S. D. technology). Product status link This high performance switch can control a load of up to 0.8 A. ACS108-8SA This device 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 Product summary the main switch. It is triggered with a negative gate current flowing out of the gate pin.
