Uh, "dummy diode"?
That's the reverse-polarity protection diode.
Good name for it, though.
Any power-supply rectifier will work. The bigger the better. The voltage rating of the part won't matter. We adopted the habit of using a 6-Amp rectifier diode in all the mobile radios we service. It gets upgraded, if the factory didn't install one that size.
Tends to prevent trouble down the line. The original 1-Amp diode shown in the schematic is prone to explode and take itself out of the circuit if you hook it up backwards without a fuse. The bigger one won't generally do that.
