Need Help Identifying Diode

(1/3) > >>

groinksan:
I received a bunch of NOS diodes. For the life of me, I can't make sense of this diode. I'm trying to find the part number for it. I tried researching the colors, but Google has a mixture of results. The packaging appear to be military-like, so I suspect the part is MILSPEC. I opened one of the packets, and zoomed in on it with a microscope. The lettering only shows "C".  Original packaging:

5960-503-4034
CE 78619
SEMICONDUCTOR DEVICE, DIODE
37-LYN-62
A- 9/62

Appreciate any help in identifying this part. Thanks!!!!

MagicSmoker:
Most likely a 1N519 (Green-Brown-White color code) Silicon rectifier rated at 50V / 1.25A.

Color codes for diodes were not entirely standardized, however, so you are right to be wary of such.

jmelson:
the numbers 5960-892-3417 and 5960-503-4034 are National Stock Numbers.  But, these may be obsolete, I can't find them in several sites that supposedly list NSNs.

I'm not surprised that Germanium diodes from 1962 would be too old to still show up there, but on the other hand the military keeps some REALLY old gear running.

I just now ran the diode through my transistor tester, the attached image is the result. Hope this helps!

bob91343:
Yup it's a germanium diode.  With only 0.4 V forward and so much leakage, it can't be anything else.  I don't think it's 1N519 as that's silicon.  So it's probably a house number, whoever'e house C is.  Continental Devices?  There were several like that.  No that would be CD.
