Looking for good, ultra fast bridge rectifier

[Alfetta87]

Hi there,

I have a PCB with integrated PSU (except the tranny), and there is a place to put a bridge rectifier (+ / AC / AC/ -), but a want something good (such at shottky, or UF4007 to name single diodes). Any idea?

thanks,
Dan

What voltage, current and application is involved on this pcb?
It is as if you're having a space rocket in your backyard and asks what kind of fuel is premium!

It's for a PASS preamp with 2SK170 (only one per channel), so it should draw very little current. 25 volts should be fine.

Ultra fast can make switching noise due to ultra-hard reverse recovery spike, I suggest go for standard silicon rectifier or soft-recovery types if this is mains frequency. Schottky may need heatsinking to avoid reverse leakage thermal runaway, they are not typically a good choice for high power rectification at low frequency as a consequence - they are used in switching supplies because they have to be, and will be heatsinked to keep them from getting hot and going run-away...

Thanks, @Mark Tillotson , for the master class.
