According to my back-of-an-envelope calculations you need somewhere around 5 Watts. I'd go with this one from RS. 5W should give you plenty of headroom. It may get hot, so mount away from meltable parts.

Edit: They carry quite a few diodes rated at >= 5W and >=20V. As long as it meets those specs, you'll be OK. Get one that will install easily.
