ACS120

ACS120 Overvoltage protected AC switch (ACS) COM OUT G DPAK COM G TO-220FPAB OUT COM G COM OUT TO-220AB Features  Blocking voltage: VDRM / VRRM = +/- 700 V  Avalanche controlled: VCL typ. = 1100 V  Nominal conducting current: IT(RMS) = 2 A  Gate triggering current: IGT < 10 mA  High noise immunity: static dV/dt > 500 V/µs – Needs no more external protection snubber or varistor – Enables equipment to meet IEC 61000-4-5 – Reduces component count up to 80% – Interfaces directly with the micro controller – Eliminates any gate kick back on the micro- controller – Allows straightforward connection of several AC switches on same cooling pad Datasheet - production data Applications  AC static switching in appliance control systems  Drive of low power high inductive or resistive loads like: – Relay, valve, solenoid, dispenser – Pump, fan, micro-motor – Defrost heater Description The ACS120 belongs to the AC line switch family. This high-performance switch circuit is able to control a load of up to 2 A. The ACS 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. Figure 1.
