bipolar semiconductor database

I'd simply support the work even if I never used it. But I may, too. Order is completed. Looking forward to seeing it.

Trying to drum up some interest in bipolar transistor database.

Have been proof-reading the contents for some time now.

Not completely finished, but trying to drum up some interest.

For those interested, there's an un-proofed list of SMD designators (well, the bipolar transistor lines are 85% checked) there too.

I've bought in too. Looks promising and if one can sort the columns then you can find your own substitutes more easily.

Thanks for the support. It's not a total waste - The old Towers publication, for example, was roughly 20,000 lines. The tehnomagazin website provides roughly 35,000 lines (seems to be propagated in spreadsheet format, as well). Most others require some kind of subscription and as near as I can make out; all could do with a sober second look at the actual data provided.

Actually there was a real book that did (somewhat) sort by various parameters - called the TRANSISTOR D.A.T.A. Book and put out by D.A.T.A. Inc. I have edition 46 (Obsolete after August 1979) which is a big help in finding subs for old transistors...23,899 types in that edition.

I guess you aren't too interested in sharing the spreadsheet...(ducking).

It's beyond my savvy, at the moment, to get the PDF printer to accept the header row of the spreadsheet as a start on each new page. I'm sure it must be possible, somehow (but I'm prepared to be disappointed).

I've also seen an interesting trick where the header row hovers on the spreadsheet display.

As is, it's impossible for me to forget the column row function. It's the sort of thing that you end up dreaming that you're doing in your sleep, pixelation and all. Do (did....) real books do that?

Frigging compeeyudahs.

If he does, I can send it out to a PDF with headings, I think. Pretty sure, anyway.

Bipolar? With or without medication?

You get E-C shorts when they aren't medicated.

Actually, it also includes MULTIPLE bipolar types, and integration of the simplest kind, like 'digital' transistors, cascode and differential pairs, mirrors, multiple base or emitter, diode-transistor pairs and elementary power modules. Descriptors can get kind of unruly.

Sometimes it gets really loud in the room, when they're all talking at once.

Depends on what kind of assistance you're able to offer, with headings and other features.

Most of the typographical errors I have noted seem to originate from a bad OCR of T.D.Towers 1980 edition (update#2).

The 37th edition of D.A.T.A. (35Meg - use 'save as') is available at:

DATA listed higher power by package derating first. I always thought that was a bit cheaky. If you've got Pd at Tc already, and a Tj max, what's the point?

Is there a more useful second format?

-separate polarity

-group power

-group by package

-list by Ft then wattage

-list by wattage then ft

No reason why it shouldn't be useful.

Not enough interest: so here's the working spreadsheet.

Prompted by another thread - how about some bootleg VBIC models? The manufacturers won't publish VBIC parameters, but those that can't be gleaned from Gummel-Poon could be measured on real devices ...

This could be your unique selling point.

The unique selling points, at this time, are that the data is proof-read and in user-configurable spreadsheet format.

Adding one single column of new data presents an enormous commitment of user input and research time, for the current 65000 line entries.

Would be better to start from scratch, using a database derived from spice models or similar - something I've already got on the go and easy for anyone to whip up. Very low line count.........

I bought a copy from your first auction...

The pdf version. Your spreadsheet version is in the mail.

How about having a 7 day Black Friday sale, say $10. I'll buy one, and FWIW I can put a link on my website. I have print copies of two of the Motorola semiconductor listings from about 1975-1980 that go back to the 1N34 and

2N107 but a spreadsheet version would be nice. I have a folder with PDF spec sheets of various popular components that is very useful but I don't think I could legally sell it or even offer it as an on-line resource because of

copyright issues.

As a sample, here is how I have these PDFs organized:

My components folder is 566 MB with over 1100 files.

I appreciate how much work you have put into your database. Good luck.
