    Question Re: What is this IC?

    How about this one?

    Looks like a diode. Tried to take pics all around by bending lead, not sure if I got them all.

    Name: Diode d.jpg Views: 1155 Size: 26.5 KB

    I used 3x zoom, then cropped as much as possible.

    I don't see anything...

    Possibly older version of the 1N4148 or 1N914 signal diode. If the body is bulkier, could be ancient germanium diode

    Is that glass or clear plastic? It looks like a fuse or a diode.

    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!
