Assuming it's not a Zener (in the regulator circuit) and is a simple
diode (probably in a bridge rectifier circuit?) then there shouldn't be
anything special about the diode other than it's current rating. I've
always operated on the principle that for diodes, current rating is
relative to physical size.
