Hi,

I have to do a simulation in LTSpice, and unfortunately I don't have a simulation model for FDT434P.
On the fairchild web page there is a simulation model, but it was the extension .mod
https://www.fairchildsemi.com/pf/FD/FDT434P.html

Could you help me please with a simulation model for this component?

Thank you.
 

Probably a PSPICE macromodel or .subcircuit. What's wrong with it?
 

I imported the model into the schematic, I renamed the component to FDT434P, but when I tried to run the project, it didn't work, because it didn't find the model.
 

Unfortunately I don't know the LTSpice method, but I think you have to establish the correct connection between the schematic symbol and the Spice model. Check how it's done with the other symbols!
 

LTSpice model files are using generic SPICE syntax. With schematic netlist entry, they connect to the symbol terminals by pin order, as with other SPICE variants.

You probably forgot to include the model file in your project.
 

this is a transistor (RET) model in pspice. You embed the model within a subcircuit. You should be able to do the same with your model.
