Can anyone help me identify this SOD80 zener diode?



(http://www.griffin.net/diode.jpg if the inline image doesn't work)


The thicker first band looks more orange to me than the red it appears=20
in this photo... but then I'm a bit colorblind so who knows.

The designator on the PCB says ZD5, so I assume it's a zener. It was=20
right at the power input to a PLC, with the thicker orange/red band on=20
the +24 rail, and the other end on the - rail.

This diode has shorted out, so I need to replace it with something.=20
Given the 'fuzziness' of zeners, I'm not sure what to use.  27V=20
nominal?  30V?

Additionally, if you figure it out... HOW did you do so?  I found a few=20
"diode color charts" online, but I can't make any sense out of decoding=20
this with those.
