SGM40666AS Overview
The SGM40666AS and SGM40666BS 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). The SGM40666AS withstands +90V/-400V while the SGM40666BS can also withstand surges up to +80V/ -400V without damage. The integrated 27mΩ (TYP) RON FET allows it to pass through 4.5A continuous current.
