Im trying to find a couple high current diodes with no need for any high voltage requirements. Im planning on trying some electrolysis to get some small quantities of Na metal. Just as a proof of concept type project. Voltage ratings don't NEED to be over 30V, but they can be. Current ratings- im looking for over 50A just to be safe, or multiple diodes, using a rewound MOT for about 10V or so. I really have no idea how much current I will be pushing yet. It seems as if i saw someone else here doing a similar large scale project, which is where i got the idea from.

50a isn't all that much current, and if you are not worried about voltage drop across the diodes just about any stud or to-247 diode should do the job no problem...

Thats just the thing, im not sure how much current to expect, and diodes really aren't all that expensive, so i can overrate it and decrease the Vdrop with a higher current diode.

You have some great schottky diodes in PC SMPS's. They are usually rated 40A or more and there are two in each package; since thermal coupling is good they are also paralellable.
