Hi all I recently purchased a bag of unmarked supposedly diodes and am trying to figure out what they are. The clues so far are normal diode action on a mutimeter but the forward voltage is high at about 1.4 - 1.5 volts. The packaging is a small square black plastic box with flat axial leads one of which has a small cross piece on it. This packaging suggests small signal or at least low power. There is nowhere for the light to come out (or in) so they are not LEDs, anybody got any ideas? Thanks Paul.

Take a picture and post it to sci.binaries.schematics ? Maybe someones seen before ?
As suggested if anyone wants to look at the mystery diode it is the top one in this picture.

The bottom one is a normal glass 1N914. Paul

Just a wild guess here, but it could be a varactor diode.
