RoHS: Compliant
View Datasheet Manufacturer Site View Pricing & Stock

The ACS108-8TN belongs to the AC switch range (built with A.S.D. ® technology). This high performance switch can control a load of up to 0.8 A. The ACS108-8TN switch includes an overvoltage crowbar 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.
