bridge rectifier pcb

[Ted205]

Does anyone know of a good off the shelf bridge pcb similar to this but with space for snubbers (cap and resistor) across the diode ?

I've had a go at making them myself but i can't get the quality i would like.

Hi, have a look there :

Both are DIYAUdio members.

Or use Schottkys and forget about the snubber

Have fun, Hannes

Ted, have you checked my group buy? See my sig below.

More current than a PCB, too.

The part you mention is a 35 A part and made out of plain diodes so I'm not sure what your point is?

Well I don't know what use it is to put TO-220 diodes on a PCB, they won't ever dissipate more than a DO-204 in the same place. If you're going to use 10A diodes, the only way to actually *use* them is with a heatsink, which is why they put the tab on the things.

I must be missing something, did I just walk blindly into an audiophoolery product?

As for snubbers, you can put RCs anywhere you like, either flying through the air or on another PCB. I'm surprised at all that there would actually be a *PCB* for *just a rectifier*, especially when it has 1/4" QC terminals just like the much cheaper, far more powerful product I linked to.

Schotkeys still have to be snubbed...or so says IRF.

Following Peter Daniel's lead, I'm going to make a bridge using individual "ultra soft" recovery ON Semi MSR 1560 (15A). But I'm not planning to use a heat sink, just connect to a terminal strip letting them just point into the air. It will replace the normal bridge in a 3-ch power amp. I should really get on that, so stay tuned for results in the next week or so. Hopefully the diodes will handle the heat.
