Need More SPICE BJT .Models

I found the following ".model" in the Fairchild datasheet for 2N5088, so
I copied and pasted it into the 'standard.bjt' ascii file in the
subfolder of LTSpice. I edited it to conform to the format of that
file, and when I got into LTSpice, bingo, it's a new transistor model in
the list.

I've been getting these one at a time, so far only from Fairchild data
sheets. So now I want to find a more comprehensive library with a lot
more BJT models. Any good place to go to find them? I've searched with
Google and found several sites but all of these have come up as dead
links, pay a lotta money, or in the case of Intusoft, a huge 1.8MB .XLS
spreadsheet, which I have to take to work to run. :-( Thanks.

I don't believe you "spice models" gets 100k+ hits, with bipolar, 2700
hits. BJT models are all over the place. I found pages with no effort
with lots of models. Why do you want loads of models that you will never
use. You can probably get away with about 20 for 99% of all design.
There's quite a few in SS.

That's the problem: they're "all over the place" and not in one library.
I've been getting 'em singly from the Fairchild data sheets, but I'm
looking for something that has them all in one library, so I don't have
to cut, paste and edit. SS = SuperSpice? You didn't say how
'affordable' the models might be. I didn't want to have to buy a whole
package just for the models, in fact I didn't want to buy anything. ;-)
It's just that LTSpice is a bit barebones if you know what I mean.
And as you say above, maybe my problem is that I'm unwilling to look
thru 100k+ hits to find what I want, which I think is a problem that
_all_ of us can identify with. Just how much time are we willing to
spend to find smoething. Well, I've already spent a bit of time, and
got something from the Fairchild data sheets; I'm just trying to save a
little time, if nothing else. Thank you. I think..

You didn't say how 'affordable' the models might be.
Very affordable, their free. SuperSpice installs with all the models I
could be bothered to get from vendors sites, although not all of them
will show up in the internal file browser unless loaded in. Have a look
in the \SuperSpice\System folder. Their simple standard text files.
Yeah, I know vendors like VisualSpice, don't allow adding of external
model files in there bare bones products, or even allow all features to
be actually used in the demo, but their twats.

The SuperpSice install is the full install of *everything*. The only
limit is save and netlist size. However, with the demo at 30 top level
components, and 25 in one level of hierarchy, its 750 total real
components, if you can actually be bothered to set up a hierarchical
design that is.

There is a fair selection of the Phillips bipolar, and Philips rf
bipolar .subckt models in the install.

Note that in SS you don't have to do anything to err.."import" models.
You just drag the file from Windows explorer and your done. The models
will show up in the internal docked browser, and you just double click
or drag their name to place them. Symbols are automatically attached for
standard spice devices. Its really piss easy.

Thanks, Terry, but I seem to have pestered enough people with my
original Q. I'm just looking for a URL of a bunch of models in one
place. I got into Fairchild's spice model web page, but I have to still
get them onesy-twosey, and then it's by email - even slower than copy
and paste from a .PDF. And since they get my email address, I end up
with a bunch of spam, which I'm unwilling to do for such meager
offerings. So I'll just keep wandering thru the URLs..

Mike E. did actually make available a zip file full of new models that
you can add to LT's existing, rather slim library. I'll repost it next
week if I can get one of my other 'puters up and running again.
Failing that, perhaps Mike will chip in here and tell us why it
appears to be no longer available from the LT site.

They
have too many to count.

Here is a page with a few on it; you can download the entire file at

Well, bless mah soul, that's gonna save me a whole lotta elbow grease.
You're the first one who's come up with something other than idle chat.
Thank you very much.

Now all I need to do is get with the program and learn how to use this
prog. I've drawn several schems including one I got from you, and it's
a q & d way to draw a nice looking schem. I haven't learned how to make
things do much, just graph Vo vs Vi for something as simple as the 45V
zener discussed here. Thanks again.

One thing you can do is build the schematics in circuitmaker, and then
use
LTSpice to run them by exporting the circuit in netlist format. You
can then
open it with LTSpice and run it.

Regards
Why can't it be run in Circuitmaker? (showing my cluelessness again, I
guess..)

I'd rather not have to switch back and forth between software packages,
for doing the same thing.

Sometimes one gets to the point where it's just not worth the hassle to
put up with limitations of freeware, and one just buys the package to be
done with it.

Not at all. I *specifically* addressed the question. I gave information
that SS ships with loads of models, that anyone can use. What part of
"Have a look

Sure, I direct people to SS to give it a go, however, for several years,
on my links page, there is a file, models.zip, clearly identified, that
contains all of the SS models, so one doesn't have to install SS to get
them.

Sure, I know you're all heart at heart, Kev. :) But seriously, there
can be problems with using other models in LT for some reason. For
example, I 'plugged in' the spice model values from the actual
datasheet of the 2N3904 into LT's library, ensuring it was edited to
the format LT 'expects' to see. No ostensible reason for it to fail,
therefore, but it did. I know not why. Upon re-selecting the original
LT 2N3904 model, however, no problems and the sim ran fine. Go figgur.

That's strange. In SS, I strip all the white space. It makes no
difference at whether there are tabs, or spaces. e.g.

is = 4.2e-12
is=4.2e-12
is = 4.2e-12

All get extracted the same way. I look for the words either side of the
"=".

Why do you think I said "by and large"?

Of course they can be some anomalys, but *most* models transport ok. For
the models on my site I did have to do a few conversions so that some of
them would run in any spice3/xspice simulater. For example,
Spice3/XSpice don't like "(4,6)" node names, which is a PSpice
construct.

Yes, I'll look for a specific example.
