sorry, my bad, side effect of posting after midnight
the part is an IRFU3711 .... had it confused with some smd fets I had IRL3714
stats:
Vgs 4.5v with an Rds of 6.7 mOhm (mili?)
I'm using the mosfet to pull-down the MCLR lines on a bunch of pics, keep them in reset until the 'master' pic is ready
The MCLR line is being pulled up to the 5v rail by a 10K resistor, and I have the gate of the mosfet pulled up to the 5v rail also by a 10k resistor, basicly so the master pic doesn't have to expend much current to pull the gate low. when the mosfet is "on" it over-rides the 10k pull-up on the MCLR and forces the line to 0V, keeping the attached pics in reset.
it seems to be working "on the breadboard", but I dont want to continue doing it this way if it's not viable for a long term design (that is, making a PCB, etc)
Since the 3711 is like $2 something a piece and rated for 110 amps, I'll probably be going with a slightly less 'beefy' and less expensive fet for the 'final' design ... or would a regular cheap 'ol silicon transistor work in situation?
