Technical content

Transient protected AC switch (ACS™) Main product characteristics ■ Overvoltage protection by crowbar technology ■ High noise immunity - static dV/dt > 300 V/µs

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 – micro-motor 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. ■ Integrated structure based on ASD(a) technology Order code

Description

The ACS102-6T belongs to the AC line switch family. This high performance switch can control a load of up to 0.2A. The ACS102-6T 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. Functional diagram TM: ACS is a trademark of STMicroelectronics IT(RMS) 0.2 A VDRM/VRRM 600 V IGT 5 mA a.
