Hello

I've found a model for the ntp60n06 mosfet, but it's a Pspice model.

I want to use it with LTspice, but there is few models sections in the
same file: .MODEL MM NMOS .MODEL MD D .MODEL MD1 D .MODEL MD2 D .MODEL MD3 D

I include the complete file, I just need the mos part of this model, not the diodes parts, but I don't know
what is the mos parts in this ntp60n06 model.

I want do a ntp60n06 LTspice model, what do I need to edit in this model file to keep only the mos part,
so I can include it in the standard.mos file and use it with LTspice ?

Thank a lot

Bye

Gaetan

Why do they bother with the notice? It does appear to be restricted from the wording.

Hello

Onsemi did pay Symmetry Design Systems to have the right to use those models and to made them openly public on their web site www.onsemi.com

But Onsemi can not remove the name and copyright of Symmetry Design Systems and replace it by the Onsemi name.

Symmetry Design Systems wrote that it's not for Commercial Use or Resale, so Onsemi or anybody can not sell those models, but they can only give those models for free.

But MODPEX are a software from Symmetry Design Systems, this software are not public domaine and are with a copyright, so no web site will give it for free.

Thank

Bye

I don't know why it would be a problem in the first place?

As far as I understand one can use the PSpice model in LTSpice schematic, using the ".inc xxxx.lib" operative, though it is not as convenient as placing a generic NMOS part and then select NTP60N06 from the menu.

so I can include it in the standard.mos file and use it with LTspice ?
The PSpice model is a sub-circuit consists of other components while the types of NMOS in the standard.mos file are specified using parameters known to LTSpice. If you are willing to spend a lot of time, it might be possible for you to deduce/workout the many parameters from the existing PSpice model and place them as an entry to the standard.mos file.

Hello

For the audio circuits where this model would be use, I do not need the diode
and other circuits around the Mosfet in this model.

So I just need the mos part of this model.

Thank
