I have this component that I believe to be a zener diode but don’t know what the lettering on it means. Can anyone help me with this. Best I can tell it says 2 U. It’s fed by 9 volts

From a sega. Don’t have a schematic. This is what the board looks like and the location of the parts

yeah, it's a diode, what type, who knows, that would require a schematic

Looks to me - according to your 'schematic' - that the diode is simply there for reverse polarity protection therefore is a 'simple diode' and not a zener.

Have you tested it and what made you remove it (symptom)?
