Guide On Creating A .lib or .mod SPICE Model For MOSFET

[Natustell]

I need a SPICE model for:

https://www.digikey.com/en/products/detail/infineon-technologies/IRF9Z24NPBF/811747


None of the models I can find are .lib or .mod, which seem to be the only types that KiCAD and recognize. I tried .spi, but I receive a "too many parameters error".

At this point, I think I need to create them myself in the appropriate file type. I can't find a speck of info on how to do this for MOSFET nor anything on the syntax and required information for a .lib or .mod. I am happy to learn, but I need to start somewhere.

Can anyone help?

It is difficult without special expensive software like ICCAP, but there are some workaround, but you have to be experienced in programming and understanding MOSFET behaviour.
