WebMar 4, 2024 · Hi! 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! WebMay 31, 2015 · Re: .model 2N2222 NPN (IS=1E-14 VAF=100 LTSpice. « Reply #1 on: May 26, 2015, 10:48:15 pm ». 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. Example: IS = saturation current. WebFeb 23, 2024 · LTspice is just using default npn values rather then your model. It is not clean solution, but you can add your model data to standard.bjt file and reload LTspice.
