ACS108-6SA-AP

ACS108-6S AC switch family Transient voltage protected AC Switch (ACS™) Main product characteristics IT(RMS) VDRM/VRRM IGT ■ ■ 0.8 A 600 V 10 mA COM Overvoltage protection by crowbar technology High noise immunity - static dV/dt > 500 V/µs G COM OUT COM OUT G SOT-223 ACS108-6SN TO-92 ACS108-6SA Applications ■ ■ AC ON/OFF static switching in appliances and industrial control systems Drive of low power high inductive or resistive loads like: – relay, valve, solenoid, – dispenser, door lock – pump, fan, micro-motor Description The ACS108-6S belongs to the AC line switch family. This high performance switch can control a load of up to 0.8A. The ACS108-6S switch includes an overvoltage crowbar structure to absorb the overvoltage 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. Benefits ■ ■ ■ ■ ■ Needs no external protection snubber or varistor. Enables equipment to meet IEC 61000-4-5. Reduces component count by up to 80%. Interfaces directly with the micro-controller. Common package tab connection supports connection of several alternating current switches (ACS) on the same cooling pad.
