I'm using Orcad PSPICE v9
Well here's what I found on the transistor I want to simulate:

I've been reading up on what a subcircuit is, and from what I understand, all those nodes are in their own little world, so they don't apply to the external circuit. Anyways, it has 3 pins, and it looks like gate is pin 2, source is 3, drain is 1.
Is that correct?
Now to put that "subcircuit" into my pspice model, I have to use the "X" function - like this:
Xmosfet 1 10 2 STB11NK50Z
where 1 10 and 2 are the "external" nodes for the drain/gate/source in that order. Correct?
Well obviously something's not correct, because I have nothing on the output now, it's a dead switch.
