Overview
The ACS108-6SN-TR, produced by STMicroelectronics, is a high-performance AC switch that belongs to the AC switch range built with A.S.D.® technology. This device is capable of controlling a load of up to 0.8 A and features an overvoltage crowbar structure to absorb inductive turn-off energy. It also includes a gate level shifter driver to separate the digital controller from the main switch, which is triggered by a negative gate current flowing out of the gate pin.

Key Features
- Enables equipment to meet IEC 61000-4-5 surge with overvoltage crowbar technology.
- High noise immunity against static dV/dt and IEC 61000-4-4 burst.
- No need for external protection snubber or varistor.
- Reduces component count by up to 80% and interfaces directly with the micro-controller.
- Common package tab connection supports connection of several alternating current switches on the same cooling pad.
- VCL gives headroom before clamping then crowbar action.
Applications
- Alternating current on/off static switching in appliances and industrial control systems.
- Driving low power high inductive or resistive loads such as relays, valves, solenoids, dispensers, pumps, fans, low power motors, door locks, and air flow dumpers.
