Re: I am unable to add and use the BS138 (BSS138) model for simulation Iin LTSpice. can anyone help me with this

I have made a VMOS model based on the Onsemi datasheet, which adheres pretty well to all the graphs. Unfortunately, I can't upload ATM, as our power has been taken out by a big thunderstorm.

And ... what is your point?
That was one of the four BSS138 SPICE models that vedhaanth648 already pointed to, yesterday, when they asked their question.? What do you make of that one particular model, and why should we think it is either better or worse than other BSS138 SPICE models?
I think it's funny that you call this one "the newest spice model" when it is in fact 16 years old.? I found many other BSS138 models which are newer than that one.? So the "newest spice model" you found is definitely not newest!? Check your facts.
But as I said previously, newness does not imply goodness.
Just an FYI -- I have four BSS138 SPICE models from Diodes Inc.? And I've got three more from Onsemi, one from NXP, and six from Infineon.? What makes any model good?? I'd say it is how well it agrees with what the part actually does, which is best determined by purchasing a few dozen samples from various manufacturers, and hooking each one up to some test equipment.
