Mur860 Diodes discontinued by manufacturer

[NaftaliG]

DigiKey still has them but less than a thousand left.

DigiKey still has them but less than a thousand left.

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

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)

Fairchild MUR860

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)

1. Wanted to use Schottky and not just Fast Recovery. Previous experiences indicated that preference.

2. Availability, and from more than one source.

3. Price, especiallly in large quantities, hundreds.

4. TO-220 Package, min 100V and 10A with large 100A+ peak.

That kinda nailed down the number of choices.

Yes, looking at onsemi, that gives:
MBR10100
MBR16100
MBR20100
MBRF20100
MBRF20200

The MBR10100 is the only single diode package

 

[till]

thats why i use MBR10100

I guess the fascination with MUR860 parts started with those two posts: http://www.diyaudio.com/forums/showthread.php?s=&postid=134303#post134303

I didn't try that many different diodes, but MUR860 was very good sounding comparing to others. Some people later recommended MSR860. Initially I got excited about them too, but more listening showed that they are too bright (especially with Cardas umbilical cord; with Kimber they sounded better).

While I didn't try MBR10100, I tried MBR20100:

has someone testes onsemi's sample program?

 

[till]

i have testes

 

[Bricolo]

i have testes

does it work good?
have you tested with your personal mail and adress, or at work?

 

[till]

this is going to be a running gag....

thank you, bricolo, my testes work well, i have 2 kids.

 

[Oscar]

Hmmm....

tes·tes ( P ) (tstz)
n.

Plural of testis.

tes·tis ( P ) (tsts)
n. pl. tes·tes (-tz)

1. The reproductive gland in a male vertebrate, the source of spermatozoa and the androgens, normally occurring paired in an external scrotum in humans and certain other mammals.
2. An analogous gland in an invertebrate animal, such as a hydra or a mollusk.

As for Onsemi's sample program, I have tested it, but my hopes are not high... They want to know what you are going to use it for, and I was quite honest... I'll report how it works out.

Oops, I just realised my error.
Of course, I wanted to write "tested"
