mini-melf diode color rings?
Hello folks,
I need to know what kind of diode is an smd, mini-melf case, glass diode with black white and green color rings on it. I've tried to find a color code on the web but seems like these diodes aren't so common. Thanks in advance. Francesco IS0FKQ |

I think it's a zener, I'm pretty sure as I measured other diodes marked as ZPDnn on the same board and all indeed are zeners. Regards Francesco IS0FKQ |

Regards Francesco IS0FKQ If you can determine the zener voltages of the other diodes, then you may be able to make some sense of the colour code. That's what I thought, unfortunately seems like there's no relation between colors and zener voltage. Probably the code just means it's a zener diode. Regards Francesco IS0FKQ |
