Hi Should 100a mosfets have a gate voltage that is the same as in the data sheet 3v min- 5v max if the parts are 4.94v gate threshold is that a good part?
I don' really know, it sounds kind of marginal to me, I answered just because I do not know how to get out of here yet, sorry
The gate threshold voltage will drive the FET drain current to some small specified value. A FET is usually driven to much higher current and a much higher gate voltage is needed. For standard FETs 10-15 volts is the usual gate drive.
