Re: What Diodes Are These?

For what it's worth, the trusty Semiconductor Cross
Reference Book (fourth edition) by Prompt Books says an RM
25 crosses to an ECG5089A, NTE5089A, or SK51V. The NTE book
says an NTE5089A is a 4.7 volt 1 watt zener diode with a 5%
tolerance.

Not sure about the second one. If you had more than two
bands I'd say read the band colors to get the value, but it
doesn't sounds like there's enough information there to go
on.
