Do you just use one in each package?
Does anyone have information on how to do this please?
You would have to show what you are trying to do because these are indeed a dual diode device with common cathodes

To make a bridge using just these would need three such pakages for minimum parts count and four to do it properly.

Thanks. I've got four so I think I'll use all 4 and just use a single diode in each packet.

I'm trying to replace the bridge rectifier with shotkey diodes. I thought this was a worthwhile mod?

Well I would probably parallel the two diodes in each package and gain the benefit of higher overall current handling and surge capability. The volt drop at high currents would be marginally lower too.

That's what I did, and I was very happy with the result. I didn't expect it to make much of an audible difference, but it did.

Thanks. Did you parallel them up?

No such thing as zero risk, but, if those diodes are OK spec wise for what you want and you wire them correctly then it will work.

Thanks. I meant doubling them up.

Doubling them up can only improve the reliability.

Just get them fitted
