Mur860 Diodes discontinued by manufacturer

DigiKey still has them but less than a thousand left.

Which manufacturer? On-Semi, Fairchild or which one? Several companies make them.

NaftaliG · 20th August 2003, 06:24 PM

Fairchild Semiconductor

I wouldn't recommend Fairchild MUR860 diodes from Digi-Key as they didn't sound as good as On-Semi parts (at least in my application)

According to a Fairchild Rep:

The MUR860 is the same as the RURP860. The only difference is the MUR was made in Korea and the RURP is made in Mountaintop, PA.

When Fairchild bought Intersil, they decided to obsolele duplicate parts.

As for how they sound???? I have to finish building my GC. I did not get the Fairchild MUR860 (as per Peter Daniel) but did get the RURP, and I have the ON semi parts on order.

I can spare 8 of the RURP if someone else wants to compare.

MUR860 isn't the only ultra fast recovery diode out there. There are many, many types to choose from. Just look at www.onsemi.com How many types do they have? Many, and this is only one manufacturer.

Has anyone tried MBR-10100 Schottkys? TO-220 package. They are available from www.onsemi.com as well:

If bought 50 at a time, not that expensive - claimed to be SOTA according to the advertising blurb. I find them to be excellent but would appreciate feedback from anyone who has also tried them. I've gotten some from Farnell. They shouldn't be difficult to find. Suggest 10A/100V version.

Yup, I prefer them to the MURs! .

I don't want to start an objectivist/subjectivist flame war, or any variant thereof, but I'm curious; how do you compare for example different rectifiers? Do you simply first listen to the original setup, then exchange the rectifiers for the new ones, set the amp up again and listen and compare it with the sound you remembered?

How do you select this specific reference, between many pages of diode references?
Whar are the required criteras for a good diode (at least on paper, for product selection in a big list)
