Default Help me find a better sub for 1N4007

Hey guys, what would you recommend as a better replacement for the 1N4007 diodes in my tube DAC's power supply?

Thanks!

UF4007. Cheap and quieter.

I'll be very boring and suggest a BY399 which is a fast "soft recovery" device.

Thanks a lot, guys! I heard Schottky diodes are also good. How do they compare with the UF4007 and BY399?

One of my favorites, and cheap and easy to find.

I can't tell the difference between a UF4007 and a high voltage Schottky at many times the price, although there are those who claim to be able to.. Might have something to do with the way I design things.. Or perhaps my tin ears?

What do you think of the HER107? The store nearby has it and will save me from having to order from DigiKey.

BTW, is junction capacitance something to consider when comparing diodes? Is lower junction capacitance better?

Hey guys, thanks a lot! I have compared the data sheets of your recommendations and it looks like they all have very similar specs. Choosing is a toss up, but I think I'll go with UF4007 as it had the most recommendations here and in another forum as well.

I happened to chance upon what looks to be a very good rectifier. Have you heard about or tried the NTE575? It's faster than the UF4007 (TRR is 70 ns compared to 75 ns for the UF4007) and it has lower forward voltage (VF is 1.5V compared to 1.7V for the UF4007). It's three times more expensive though, 70 cents a piece. Do you think it is good and worth the higher price compared to UF4007?
