Back when I was learning electronics they told me that unless you've got
them matched really well you NEVER put diodes in parallel, especially
rectifiers. One of them will get more current than the other(s) and be the
first to fail.

These days I see it done all the time, mainly with LED's. Perhaps something
has changed while I wasn't looking?
