Last time I tested several 2N7000 Spice models (2005), there was huge
variance between them, and some down-right non-physical behavior.
Has anyone found a better 2N7000 model since then?

The 2N7000/2N7002 parts themselves vary a lot between manufacturers,
which is why some of our products specify a specific manufacturer for
these parts.
What non-physical behavior are you seeing?
All but the Supertex model failed to model ANY behavior below
threshold, and the Supertex model had discontinuities in the ID/VDS
curve blending... guaranteed to cause simulator convergence issues.

I forgot to reference my old post (4/6/2005)...

Second page tells it all.

Attached is an old Infineon lib of FETs, etc that may be of use.
