You are looking for Bipolar transistor or MOSFET?
If you are looking for VDMOS and Diode modeling from datasheet. I knew Hendrik Jan created a program VDmostool to create VDMOS model from datasheet. In his website, there is a comprehensive guideline how to generate a VDMOS model from datasheet, scroll to bottom of this website, downloads section, you can find the guideline in pdf and the program.
This is his website, forum may not allow to use website link with ip address only.
