BD131 Spice Model Wanted

Hi all,

It still amazes me after all the years LTspice has been around the 
standard parts library in it remains so tiny. I don't think this long-
standing defect in otherwise very good program will ever be fixed.
So like anyway, has anyone got a model for a BD131 NPN transistor they 
could post here?
TIA folks.

I searched for it and found on the NXP site that it is EOL. I doubt that 
any further search will turn up a spice file for that device. I hope you 
have a bunch of them on hand.

The lack of parts is not a defect of the program. Can't you find the model
on the manufacturer's website? That's where the LTSpice distribution would
get it from, anyway.

I provide a link... LTwiki of all sources... BUT LTspice historically
only provides models for their own line of chips.

Wow! Great stuff, Jim! Many thanks for that.

Thanks for your inquiry!  It lead me to discover that link ;-)

What's the highest 2N number now? 7500 at least. Then there are all
the non-2N parts, the 2SKs and the BCXs and your BD thing.

Hardly a "defect" to not have 15,000 transistors in the library. And
LTC isn't selling transistors!

Just pick something similar. Or create a model.

"Defect" was perhaps the wrong word. *Shortcoming* would be more 
accurate. It's only a minor peev, anyway. Mike E and Linear have done a 
sterling job on this project and deserve huge praise for their efforts.

I wonder if there's a simple way of taking the contents of that bulk file 
Jim pointed to and adding all those models to the existing LT library? 
Anyway, I've saved the *lot* to a thumb drive; a very useful resource 
indeed. :-)

I saved them to C:\PSpice\DeviceLib\BJTs\LTwiki_BJT.lib

I wouldn't add them to an existing LTspice library because LTspice,
during updates, overwrites some of the existing libraries... and
encrypts many of those that haven't already been encrypted >:-}

I noticed that right away, and saved the unencrypted libraries
"elsewhere" ;-)

To use that BJT library just include a "Spice Directive" in your
schematic: ".LIB C:\Path(s)...\LTwiki_BJT.lib"
