Transistors

Here are the user models I've collected. I only want to add user created models here; this way, the models have been scrutinized and are more likely to be close in performance to the actual devices.
  • Models from Andy_C, probably very accurate:

  • Models from Christer, very simplistic, give very good performance in simulator (perhaps better than the actual devices?). Christer himself did not guarantee the accuracy of these.

.model 2SD669_Christer NPN (IS=5p NF=1 BF=250 ISE=5p NE=1.5 IKF=3 VAF=150 RB=1 RC=0.25 RE=0.25 TF=1.14ns CJC=50p )

  • Keantoken modified these models of the 2N5769/5771 complementary HF switching transistors. The models are very accurate regarding DC characteristics but the AC modeling wasn't modified from the original model. Here is the thread: http://www.diyaudio.com/forums/softw...ity-check.html

.model 2N5769_k NPN(Is=1.2f Xti=3 Eg=1.16 Vaf=100 Bf=88 Rb=45 Ikf=200m Ise=33f Ne=1.7 Xtb=1.7 Br=1.365 Nc=2 Isc=0 Ikr=0 Rc=.6 Cjc=2.83p Mjc=86.19m Vjc=.75 Fc=.5 Cje=4.5p Mje=.2418 Vje=.75 Tr=1.073u Tf=227.6p Itf=.3 Vtf=4 Xtf=4 Vceo=15 Icrating=200m mfg=Fairchild)

  • Also by Keantoken, but not as accurate as the 5769/5771 models. Hfe is optimistic.
