I have a 25 amp 12/24 2 battery charger that someone hooked a battery to backwards. It popped one of the 4 diodes off the heatsink plate, and it looks OK other than that. One of the diodes is between each of 4 winding wires and a heatsink plate. These diodes attach to the plate with a pop rivet, and had some white heat conducting grease like material between the diode and the heatsink plate. What I need to know is what do I need to replace this diode. The writing on this one and the others is gone except for a U94... readable on one of them, the word Mexico, and the arrow showing the current flowing to the heatsink. I'm good with the soldering and I have a 6-32 nut and bolt to replace the rivet. I could just walk into Radio Shack and drop what's left of this one on the counter and hope for the best, but I would rather go in with a number or some sort of info as to what I need. It is an older off brand charger, labeled with something like "The world,s best bass boat battery charger." and a company name here in the USA. I can get more information off the charger if needed, I just don't have it right here now. Online searches say "just make sure it's bigger than the original and you'll be OK." The problem with that is I don't know how big the original is. Physically it is about a 3/4 of an inch long tinned blade with the pop rivet hole then the 1/4 inch diameter x 3/32 long can for the diode sandwiched between blade 1 and another blade with a smaller hole that the winding wire was soldered to. I think you would smear some of the conducting goop on blade one and attach it to the heatsink with the pop rivet then solder the lead from the winding to the other blade. Can you give me any help with a part desription or number or ball park rating to ask for or anything here guys?
