ACS120-7SB-TR AC Switches by STMicroelectronics

Overvoltage protected AC switch


The ACS120 belongs to the AC line switch family. This high performance switch circuit is able to control a load of up to 2 A. The ACSâ„¢ switch embeds a high voltage clamping structure to absorb the inductive turn off 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.
