Overview
The ACS108-6SA is a high-performance AC switch developed by STMicroelectronics, utilizing A.S.D.® technology. This device is capable of controlling loads 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, ensuring reliable operation. The switch is triggered by a negative gate current flowing out of the gate pin, making it suitable for various applications requiring robust and efficient AC switching.
