Description
The ACS108-8SA 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.
Product status link
ACS108-8SA
This device 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.
