Can I use a 5-pin 3-phase bridge rectifier to achieve full-wave rectification of single phase supply?

Thank you,
Mark

Never did it myself, but should work if you only use 2 of the inputs and then the DC output terminals. I do need to ask about you saying "6 pin" shouldn't that only be 5 pins/terminals? All I looked at online use either 5 or 7 terminals.

Sorry, you're correct. It's 5 pins.

The bridge is rated at 50A. I presume each individual diode needs to be capable of this amperage, so using just two inputs won't reduce it's rating. Correct?
