Is there a rule of thumb stating how much power an N-Channel MOSFET's
internal body diode (anode at source cathod at drain) can handle vs.
the normal use drain to source power rating of the device?
Does this make sense?
I am using an Nch MOSFET to switch a load to ground in a battery
operated project. The design does not allow me to place a rectifier
diode in series with the load to prevent current flow through the body
diode in the event of reverse battery connection. I was wondering if
the battery was connected in reverse, would the load limit current
enough to save the device? Unfortunately I never see the power rating
(or forward voltage drop of this diode) published in manufactures data
sheets so i have no way to tell.
Thank you in advance,
