If the current is 2 - 3 amps, use 1N5404. They also drop 0.7v and cost about 25 cents each. You will need to heat-sink all the diodes.
The way to heatsink a 3 amp diode is to use a strip of PC board 5 - 8 cm wide. Cut the copper with a saw to create separate lands and drill holes so that the leads can be soldered to the board. Keep the leads fairly short. Each diode is going to dissipate 2 watts, so keep them apart.
How do you effectively heat-sink a 1N5404? I guess it would be better to use a diode in a TO220 package.
It's fairly pointless talking about heatsinking, when we don't know anything about the actual problem - it's vague in the extreme.
This will overload some devices.
request has been for a stable voltage of 48v and I have suggested the simplest solution is to clamp a number of 20 amp bridges to a heatsink and allow each bridge to drop about 1.4v
