SGM40664 Overview
The SGM40663/4/5/6/8/9 are over-voltage protection devices designed to protect low voltage systems from damage with a high voltage supply up to +31VDC and +40VPEAK (10s with 50mA current limit). They can also withstand surges up to +110V/-400V without damage. The integrated 28mΩ (TYP) RON FET allows it to pass through 4.5A continuous current.
