Schottky diode SPICE model?

[Stuart Brorson]

Does anybody here have a Schottky diode SPICE model which they would
be willing to post? I am looking for a model describing a
small-signal Schottky which might be used in a non-linear transmission
line. Barring that, how about a Schottky static protection diode? A
diode of around 100um^2 area on Si would be just peachy.

I have indeed Googled for a SPICE model, but I have mostly found large
honkin' Schottkys used for high-current power applications which are
not useful to me. Therefore, I thought I might turn to the community
of experts. . . . .

Thanks,

Stuart

I don't know, but I'd like to hear more about your NLTL. Speeding up leading
edges?

Here's one for the BAR42 I found in the diode library for the SPICE I use:

..model BAR42 D(
+ IS=1.13853e-08 ISR=3.26235e-08 RS=0.99517
+ CJO=9.26191e-12 VJ=1.6 M=0.411631 BV=33 EG=0.7 )

Thank you!

Agilent (formerly HP) makes serveral lines of small Schottky diodes,
and their data sheets includes SPICE parameters. Take a look at
