I've been looking for datasheets for various transsistors with limited
success. Is there a reference book I can buy that has detailed info on
various transistors? I found lots of info on 2n2222 and 2n3904
transistors, but no luck on less common ones like 2n3866. I need info
on input and output impedances to be used in matching networks. Thanks.
Well, Allen, the 3n3866 has been discontinued for many years, if not
decades! But I do have 10 different data sheets in my collection.
An old Motorola 6-page version has 19 figures plotting admittance vs
frequency among the various parameters. A newer 4-page Motorola data
sheet is missing most of those figures, but instead has s-parameter
Smith charts that look useful. A 9-page Philips sheet has lots of
circuit diagrams reminding me of the old RCA data sheet.
I'd be happy to email you those three data sheets if you like.
As for databooks, it's hard to get them out of manufacturers these
days, so flea markets and eBay auctions have become prime sources.
But ON Semi (formerly Motorola) has their recent databooks online,
http://www.onsemi.com/site/support/literature/list/0,4858,databooks_0,00.html
For example, you can download DL126-D, which is a 1135-page Small-
Signal Transistor Databook, and DL110-D, a 1449-page RF & IF Device
Databook (but it won't have an old 2n3866 in it). But watch out,
these are 15.4MB and 18.9MB files! Actually not bad, considering
the number of pages and the amount of graphics contained therein.
Thanks,
