ACS120 Datasheet | STMicroelectronics

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 m A - High noise immunity: static d V/dt > 500 V/µs - Needs no more external protection snubber or varistor - Enables equipment to meet IEC 61000-4-5 - Reduces ponent 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 - 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. Functional diagram OUT G mon drive reference to connect to the mains Output to connect to the load.
