Here's my model: .model 2X3055FAKE NPN(Bf=73 Br=2.66 Rb=.0000001 Rc=.0000001 Re=.0000001 CJC=1000P PC=.75 MC=.33 Tr=.5703U Is=2.37E-8 CJE=415P PE=.75 ME=.5 TF=99.52N NE=1.26 IK=1000 Vceo=60 Icrating=10 mfg=STMicro) | |

| Sep 14, 2022 at 13:14 | comment | added | ChristophK | Really nice answert, thank you! Only one thing is still unclear to me (the main thing): How do the values of Rc, Re, Rb relate to the Ebers-Moll equations? Are they "out of scope" for the equations and have to be considered separatly? Or are they included in the equation in some of the parameters? If yes, which one? I have read your other post but didn't find the answer. | |
