    Hello,

    I was looking through my part bin and found this part, which I believe might be a diode, but I am not sure what to make of the band markings.

    From this source I would assume this would be a 1N914 but its hard to make out the second band and I thought it looked brown.

    Any ideas?

    Thank you!

    The stripes say, "914". Measure it with an ohm meter and see if it has 910k of resistance or if it is a diode.

    Current flow is unidirectional towards the white band.

    Looks like 1N914, smells like 1N914...

    I've never seen a 1N914 or 4148 in that case colour.

    I do have a ton of old 400mW zeners which look very similar though.

    I would use a zener tester, or if you don't have one you can use a DC supply of 30v or 50v etc and a 10k resistor in series with the diode. Most zeners are under 50v especially in 400mW size.
