I have a 12V power source that can deliver 25A (DC). I intend to use something around 15A .. 20A on a circuit that includes a diode. However, I can't find a diode that can handle that much current, and I've seen people recommending bridge rectifiers instead.
I happened to find a KBPC50005 bridge, which is rated 50Amp / 50V.
However, I'm not sure how to make the connections to get something equivalent to a 50Amp diode -- there are two ways, as far as I can see:
This is what I suppose:
- the second setup would result in a higher voltage drop (because I would be using two paths, each with two diodes in series). In the first setup (A-B), I would be using a single diode, so a lower voltage drop;
- the second setup would be equivalent to diodes in parallel, so it would perhaps allow for an even higher current. The diodes are in a single package, so the usual problems with diodes in parallel would not happen;
Am I wrong?
