RD-10 EB diode replacement

[Zekeman]

There are a couple RD-10 EB diodes on the driver board of an AU Dash nine 900 amp… Can anyone suggest a suitable replacement?

Thank you very much!

Happy Thanksgiving!

According to the NEC datasheet RD-10 EB is a Zener: 0.5W with a Vz between 9.19V and 10.30V - possible sub is BZX79-B10 or BZX55-B10

OEM 500mw 9.2 - 10.3 volt --> RD10EB

This one is a little tighter tolerance of 9.3 to 9.7 vdc

Agree - good sub -

I just found a bunch of tzx9v1d'a in my drawer....it appears this would work as well?
