They don't give SPICE parameters in datasheets. (Except when they do.) You have to look up the definitions for everything, and set up test cases in the simulator to produce a model fairly close to the real thing.

I want to add BDX53C and BDX54C to LTSpice. I saw some tutorials and tried to add transistors by typing their info to standard.bjt file but I think they do not work properly, when I run the DC op pnt analysis their beta values seem to be around 100 but they are supposed to be 750. Thank you!
