Hello, I've got a shematic of an eletric circuit, but I can't find one
typ of (zener) diod. It's also difficult to read the name of the part.
It must be something like SM6530 or SMB530 or SM6590.

I need a data*** of the part.
Thanks for your suggestions!


SMB seems likely. As to the rest, I don't know. If this schematic is paper,
try bright light. Seriously bright, sun or close range metal halide. Try
different angles of light, anything that might reveal more traces of the
damaged text.

Also, look at the circuit context. It is like either a voltage reference,
in which case a schematic might indicate a test or reference voltage point
that you can work from. Or, it might be a transient voltage suppressor. If
you're trying to repair something, there's a good chance that this is what
it is, and an overlarge transient is probably what killed it.
