Each diode carries the full current, but only half the time. So if it is going to have 25 A continuous through it, I would look for a 30-35 A diode rated for at least 200 V (120 V-RMS is 170 V peak). > It just seemed easier to buy a rectifier than to build one. > But to get 25 amp, I may need to build. It's easy to build. Four diodes is all it takes. Here is a link to a diagram for a bridge rectifier. https://en.wikipedia.org/wiki/File:Diode_bridge_smoothing.svg That diagram is the article: https://en.wikipedia.org/wiki/Diode_bridge The advantage to a pre-built bridge is it's easier to wire. And occasionally it's cheaper. As Craig said, there will be a fair amount of heat from these diodes, so be sure to mount them in a way to dissipate that heat. -- Philip _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
