I've been looking into selecting a one-piece square bridge rectifier for the 30V/3A power supply project. There seems to be lots of these like every other component type! Generally, they seem to have rather heavy voltage/amperage handling abilities.

What is the downside to using a bridge with significantly higher ratings than required besides slightly higher cost and larger physical size?

Would a bridge with just adequate specs put out more heat than one with much greater than required specs?

A higher rated bridge will more easily tolerate voltage transients and startup surges. Also it may have a slightly lower voltage drop.
