RURG3060C replacement

spooney · 17th April 2011, 09:25 PM

Working on an Earthquake 200DHC Mark 2 for a buddy and one of the RURG3060C rectifiers has snapped a leg. The part itself is still good but I would rather just replace it than try to solder the leg back together. Is there a good sub available for this part? It appears that these are hard to find

Yeah just one but I would be willing to buy a pair if you would be willing to part with them.

EDIT: Sorry, mine are actually RURG3020C. I don't see why a car amp would need 600V diodes though; 200V should work.

spooney · 17th April 2011, 10:28 PM

Is it the same case style? I agree that the 600 volt may be a bit overkill

theAnonymous1 · 17th April 2011, 10:42 PM

Yeah its the exact same TO-247 case dual diode, just the 200V version.

PM me your address and I will send you a couple.

Does everyone agree that the rurg3020 will be a suitable replacement in this amp ?

Well, he asked for RURG3060C which is a dual diode.

Spooney, does it have two pins or three?

Hi Guys,

I'm guessing this is a rectifier on the output of the step-up SMPS in the amp? If so, you should really stick with the 600V rating on that part. I've seen +/-75V SMPS that had well over 400V of ringing on the diode, even with proper snubbers.

600V parts would have higher losses than a 400V or 200V part, so there's likely a very good reason they were chosen. They wouldn't be there unless they were needed.

I'd bet if you put the 200V parts in there, they'd self destruct in no time.

Take a look at the Fairchild Stealth line-up. There's likely one in that series that would drop in.

Cheers,
Owen

The amp has 80v of rail or less. I think the 200v would work. If they're being used in the amp that theAnonymous1 has, I'm sure that they're OK.

The rectifiers I listed have dual diodes.

The RURG3020 is available from Future also.
