Overview
The ACS120-7SB from STMicroelectronics is a high-performance AC line switch belonging to the AC line switch family built around the ASD™ concept. This device is designed to control loads up to 2 A and is particularly suited for applications requiring robust and reliable switching capabilities.
The ACS120-7SB features a switch integrated driver, high voltage clamping structure, and a gate level shifter driver, which separates the digital controller from the main switch. It is triggered by a negative gate current flowing out of the gate pin, ensuring efficient and reliable operation.
