PSpice model for 2SK2145

[Falkomat]

Hello,


I recently downloaded micro-cap and I am playing with it for now.
Does anyone know where to download a Spice model for the Toshiba 2SK2145-gr JFETs?


I think I am not clever enough to find it. 🙁


Thank you in advance!

2SK2145 is a dual JFET containing 2x 2SK209 with their source wired together internally
Try a pair of one of these models:

.MODEL 2SK209BL NJF (BETA=21m BETATCE=-500m CGD=7.762p CGS=14.01p IS=2.613f
+ KF=.4244f LAMBDA=6.15m M=384m PB=375.4m RD=12.194 RS=16.746 VTO=-786.9m
+ VTOTC=2.5m)

.MODEL 2SK209GR5 NJF (BETA=17.136m BETATCE=-500m CGD=7.762p CGS=14.01p
+ IS=2.613f KF=.4244f LAMBDA=2.62m M=384m PB=375.4m RD=1 RS=1 VTO=-550.86m
+ VTOTC=2.5m)

.MODEL 2SK209GR-K NJF (BETA=21.85m CGD=14.58p CGS=14.78p IS=2.613f KF=.014f
+ LAMBDA=6.15m PB=375.4m RD=12.194 RS=13 VTO=-535.9m)

Thanks for the 2SK209 models. Especially that you have different models for the different grades. It will be interesting to see the differences between them and the 2SK170 models I have been using.
