Motorola 365 Transistor

Does anybody have any data for a Motorola branded transistor in a metal
TO18 can with just the Motorola logo and 365/026 marked on it
and "KOREA" stamped in the top.  Google provides plenty of hits but no
help.  Every man and his dog seem to be trying to sell them though !

I've also found a couple of very interesting Ferranti IC's that I can't
identify, but they will have to wait whilst I can photograph them.

Thanks in advance.

It sounds like a house number. Somebody ordered a few million or so, marked
with their proprietary house number, and either the product died or the
company went belly-up, ergo, millions of overstock.

I'd guess it's either a 2N2222/3904/4401 sub, or some exotic thing. Can
you get one and run its curves, etc?

Good Luck!

Hi Rich,
Thanks for your suggestions.
At the moment I don't have access to the test gear to be able to do
that. This transistor, there is about a 100 of them, is part of a very
large consignment of semiconductors that I acquired as part of an
auction lot a few years ago. I'm only now getting round to examining
them. There are several hundred VN46A power fets as well as things
like PUT's & UJT's in there. It would be nice to know what these
devices are.

I really must make an effort to photograph those "Ferranti" IC's.

It's easier to measure V(be). That tells you Si or Ge.

OK ! Got the AVO out...
Silicon PNP EBC pinout.
I still don't know if its LF, RF etc. Yes I can measure the Hfe but I
haven't tried... Yet !
I suppose I ought to start and catalogue them...

Hfe can be measured with a VOM (Multimeter).
Can leakage current be measured with a Multimeter also?

Sure, and a variable power supply and series resistor. But you've got
to have a pretty sensitive current range - leakage is probably in the
microamp or less range.

Good Luck!
