This is a pretty generic replacement.

The ones I have in picture work great. 90Amp Isolated base is handy.
Unfortunately they are half bridge, so I have to waste two of them to repair a charger.

I'm looking for some common anode devices

 

I don't get it, why the link to the rectifier-assembly, if trying to upgrade to the "lug-type" diodes?
I didn't see any reference to a model or series type for these diodes.
I dabble in electronics, and am a bit naive.
My friends charger has near the same specs, and I'd like to switch over to 2 lug-type diodes, since button-type diodes are
very hard to find.
Charger/starter 40/20/5 200a, with 6 to 12 volt options.
Can anybody suggest a couple of specific types of diodes, Please.
