I have a car battery charger with bad button diodes, I tried using a smaller diode (based on ohm reading), but broke off the soldered tabs in the process.

I have scavaged some rectifier diodes 1N5408 (I have 4 of these), and RG4 (I have two of these). Can I use these in place of the button diodes?

I couldn't find 1N5408 on the Datasheet, or Alldatasheet web sites.

Thanks,
Gary

 

Okay, my mistake, I found the 1N5408 on Alldatasheet, and I think that they might be a good ones to try. Any advice on replacing button diodes with these stem types?

Thanks

 

What's the "charge current" rating on the charger? The 1N5408s are only rated at 3A.

When you look for high current rated diodes, a bridge is often less expensive than a pair of diodes.
