Don't those diodes handle surges anyway?

Yeah, the surge rating is massive.

I mean a 3A diode will take way more than that for a fraction of a
second.

Yep.

It's the heat that kills them.

Not with bridges.

So why don't they just fit what they need to instead of bigger ones?

The bigger ones are the same price.

Its only when you got to the big ones
potted in a square aluminium thing with
a bolt hole in them that the price increases.

that's a trimmer

No, a trimmer is an adjustable resistor/capacitor/inductor:

Rod was talking about a very large diode.

no its not

Then you'd better correct Wikipedia.
