I've never used a mfr model that was a subckt before; I've always added the .MODEL to the LTSpice library file, or edited an existing device.
This Vishay MOSFET has a more complex model though, and she ain't loadin' Jim. LTSpice says it can't find the model for M1.
I even tried putting the definition right in the .asc, still no joy.
I followed the LTSpice help info, as best I could. Any obvious goofs?
Thanks, James Arthur
