Old transistors data sheets - Where?

Threaded View
I came across a large box of unused assorted transistors in a box of junk
from a TV and video repair business that had closed down and left them all
at our rubbish tip trash and treasure exchange. Most are new although some
are rather superficially corroded on the metal cases.

I have searched at http://www.alldatasheet.com/ to identify the components
and have had some success, but many of them do not show an exact match.
Although I am a telecom engineer, and know a bit about them, I haven't had
much to do with  such components for quite a while.
I want to make use of some in a couple of projects, but lacking the data
sheets I'm not sure what is what, although many are obviously power
transistors of some kind.

Is there a good source of data sheets for older components other than
http://www.alldatasheet.com /

Sometimes the above website comes up with similar numbered components but
they are obviously different components, just from the physical appearence.
Here are just a few I can't exactly match. Figures after the comma are
secondary numbers listed on the components under the main mumbers.

Sanyo C1050E, 5k
Sanyo B407 tv, 4g
Sanyo SD68C, 5A
Sanyo D416, 6B
SonKen 25D201
    D621M, 8E
NEC 2SD388, R57
Sanyo 2SD68C, 4J
Sanyo C1050D, 5G
Sanyo C1050E, 5H
Sanyo C1050E, 5K
Sanyo C1050D, 5K
    BU326A, T8947
NEC 2SD388, K3YA
Matsushita 2SD198

These are just som examples which may show the age of the components, there
are literally hundreds of others, transistors big and small.
Can anyone suggest where I might get datersheets on these "antique"
components please?

As an example, google on "2SC1050 datasheet" (drop the trailing grading letter)
and you'll get a zillion datasheet hits - well, 270 in English anyway.

I use a publication called VRT  (ISBN 981-214-126-X) which lists the main
characteristics as well as equivalents.
Altronics stock it.

I use this one for original datasheets:
 http://www.datasheetarchive.com/search.php

... and this one for cross references:
http://nte01.nteinc.com/nte/NTExRefSemiProd.nsf /$$Search?OpenForm

Otherwise you can Google for PDF filetypes, eg "2SD388 filetype:pdf".

You could try datasheetarchive http://www.datasheetarchive.com/

I find that they usually have somesort of data on even nondescript devices and
they are adding new stuff all the time.

Re: Old transistors data sheets - Where?
Just tried http://www.alldatasheet.com/ with the Sanyo C1050E, 5k which is
really a 2SC1050E with no probs ,  note from memory most of those tranistors
had the 2S dropped so C1050E  is 2SC 1050E ...same goes for most of the
other tranistors.
