Zener Diode identification help please
« on: February 14, 2018, 03:29:20 pm »
Hi, I have just taken a Zener diode from a Toshiba DVD Recorder Power panel. The only marking is 27B. Can anyone help with further identification to find a suitable replacement please.

Where is the zener diode located? It could be a 27 volts zener.

Edit: saw that you mentioned power panel...

Without seeing the part I would also vote for a 27V part.

Depending on the package it could also be either 1N5227B (3.6V) or 1N5927B (12V)  :-//

is it bad?  If you have a variable power supply and some resistors you can test it.
