BF959 SPICE model

Has anyone got a SPICE model for the On Semi (was Mot.) BF959? I and someone
else who is interested in using this device can't find one anywhere. I've
bought 2000 of them very cheaply on eBay. :cool:

Circuitmaker claims to provide that model. Know anyone with
Circuitmaker?

I love to cook with wine. Sometimes I even put it in the food.

Terry,

Where did the file come from? I posted my model taken from it to the QRP-L
list and someone wanted to know.

Having a library of SPICE models for all devices would be a very valuable
resource. Fairchild has a full library for just about every device that
they have made, but unfortunately this is not one of them.

Chris/Leon: It came straight out of the model library in CircuitMaker
2000.

Thanks very much for those parameters, Terry.

I've put them into standard SPICE format:

..model BF959 NPN(IS=10.2e-15 BF=78.00 NF=1.000 VAF=80.50 IKF=60.00m
ISE=16.80p NE=2.000 BR=4.000
+ NR=1.000 VAR=12.00 IKR=90.00m ISC=0.000 NC=2.000 RB=2.060 IRB=0.000
RBM=0.000
+ RE=515.0m RC=206.0m CJE=1.740p VJE=1.100 MJE=500.0m TF=227.0p XTF=0.000
VTF=0.000
+ ITF=0.000 PTF=0.000 CJC=2.250p VJC=300.0m MJC=300.0m XCJC=1.000 TR=158.0n
CJS=0.000
+ VJS=750.0m MJS=0.000 XTB=1.500 EG=1.110 XTI=3.000 KF=0.000 AF=1.000
FC=500.0m TNOM=27.00)

It seemed to work OK when I added it to the Pulsonix SPICE library and
pasted the device into an existing schematic.
