In Reply to: RE: hyper or ultra fast soft recovery with axial leads? posted by Tweaker456 on March 10, 2016 at 10:34:34
I use UF or Schottky types. "Hyperfast" is a term usually applied to Hexfreds. My bias is that those don't sound quite as clean as UF or Schottky types. I have no idea why, but a real EE could tell you why.

Thanks for your opinion Lew. The Hexfreds I used a very long time ago in a previous audiophile life sound great but I never compared them to Schottkys. I don't see any freds with axial leads. Finding at least some Schottkys with axial leads is easy. I read that someone thinks the Cree silicon dioxide Schottkys are the "best". Of course they do not come with axial leads as far as I can tell. Why the packages is these parts is so limited I don't know. Tweaker
In the low voltage ratings you would need for the Trip Lite, I believe you can indeed get axial-leaded Schottkys. Whether or not they are made by Cree, I do not remember, but I have some in my stash.
I think I'm going to go with the Vishay SBYV ultra fast soft recovery diodes , which are axial. Took awhile to find. If they are anything like their mf resistors I'll be happy. Tweaker
Vishay-Dale are a big company. They make all sorts of electronic parts, including those nude resistors, but not every single thing they make is an attempt at state of the art, notwithstanding those resistors. Anyway, I am sure those are fine diodes.
To bad nude is so hard to afford.
Yep, they're expensive at about $10 each from an on-line source, but I would sooner spend my money on nude Vishay resistors than on bags of colorful crystals.
There are a lot of people out there who would agree with you on that. Some dead. One reason Schottkys do or may sound better is from what I read there is nothing to recover from softly or otherwise. One person with lots of opinions and confidence tells me its the soft recovery that's important and uses the sr diodes. Sure sounds like nothing to recover from might be better. My worries about voltage and overheating of Schottkys are over, I think. On Semiconductor has 10A 200v Schottky and Mic has 10a 1000v. They likely should never see more than 31 volts. Tweaker
Because industry is going to surface mount. If there were a significant number of buyers wanting axial lead parts, they would make them.
