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(1) 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 1.

can occur on the electrical network.
2.1.1 High inductive load switch-off: turn-off overvoltage clamping
With high inductive and low RMS current loads the rate of decrease of the current is very low. dissipated, the ACS voltage falls back to the mains voltage value (5).
