    I bet it is a germanium diode.

    You can confirm it by applying say 10 volts with a 10K resistor and measure the voltage drop on the part pins. If it is around 0.2-0.3 volts the you can be sure for that.

    I'm thinking germanium too, but even then, google seems to believe there isn't a standard bar code.

    They look an awful lot like theses guys:

    I still have to test the voltage.

    I had to have a quickie look. Used 2 meters on diode mode and got these readings:

    Name: Diode Aneng DT9205A.jpg Views: 1141 Size: 180.1 KB

    Is the top one measuring resistance (339)?


    Name: Diode TES-2712.jpg Views: 1159 Size: 142.0 KB

    And is the bottom one measuring voltage (0.282)?

    Then germanium it is!

    These used to be the AM detector diode commonly used in transistor radios in the 80's and early 90's

    Then, Jerson, I bet you are around 60's ?
