Bloody Mouser!

[Cursitor Doom]

I can't get any sense out of Mouser's website. You'd have thought
finding a diode would be simple enough; the spec ain't that hard to
meet: 600V 3A fast recovery diode with through-hole cylindrical
encapsulation. Can I find one on their site? Nope! Seems they don't
stock them any more.
The original part number was SR3523 but no data available on the net!
Anyone got any old diode data books to hand?

Got a whole sheet of them. Just use the filters.

None of those are fast recovery types, though. And on my browser at
any rate, the filters keep clearing by themselves.

Nothing to do with Agent. I'm trying to find the part I want on
Mouser's website with Firefox or Opera - and failing badly.

I just looked at your message headers and saw your Agent browser. I
should be more careful.

Which, of course, was the third one down on the list I linked. I guess Paul realized that you need your information spoon-fed.

There's nothing in the description given which indicates this is a
fast recovery type and Mouser do generally state that if it's
applicable.

[ehsjr]

You need to check the datasheet to find that info.

Well, quite. There doesn't seem to be any consistency in the details
listed by Mouser in the 'description' column. They *usually* state if
a diode has a fast recovery time in that column - but not in the case
of this particular diode for some reason. :-/

UF, hmmmmmmm... could that mean "ultra fast"?????

Spoon fed.

Could have but might not have. The original part had an SR prefix. Use
your powers of divination to work out what that means, since you're so
gifted.

SR, back in the day (remember, the OEM number is obsolete) = Silicon Rectifier. Back in the day, that meant something.

As in: 1N4007 is a standard silicon rectifier at 1A at 1,000 volts.
Whereas an UF4007 is a fast-recovery silicon rectifier at 1A at 1,000 volts.

Make an effort. "Poor me" just does not cut it.

[Cursitor Doom]

Make an effort? The page you linked to had 90 devices listed and I
would have had to read through up to 90 datasheets to find the right
one out of that lot. So yes, that certainly *would* have required an
effort!
Paul gave a precise and succinct answer to the question which saved me
a lot of time. If that's "spoon-feeding" then I'd like to see a lot
more of it on Usenet.

Correct.
The legacy purpose for usenet is for folks to help one another.

You'll receive no help frpm Peter Wieck ... just crude, snide comments.

[ehsjr]

I hear you, but that's why you need to try different approaches.
I found that diode by the following argument in the Mouser
search box: diode 600V 3A fast through hole
That brought me to a page that showed 47 diodes - scrolling
down it was the third diode pictured. There are a lot more
shown that would meet your needs. Learning different approaches
to searching the supplier's sites is often helpful. That
does not deny the fact that it can be a pain in the butt.

[Cursitor Doom]

I think you're 100% correct. Being in the UK, Mouser is my supplier of
last resort as it's far more expensive than European sources.
Consequently, I rarely visit the site and never get enough familiarity
to find my way around its various little quirks.

The UF5406 is a pretty generic part, is there not a supplier in the UK that
carries it? Like RS Components?

https://uk.rs-online.com/web/cp/6290007,9189203/?pst=UF5406-E3%252F54

With apologies to Mr. Wieck, if I'm being too helpful.

RS have been around a *very* long time in the UK, along with a bunch
of others such as CPC, Farnell and whatever. However, their delivery
record is not good. At least with Mouser, although it has to come all
the way from Texas, it's trackable and gets to me quicker than RS can
manage. U-S-A! U-S-A! U-S-A! ;-)

[Paul Babiak]

How is Digikey for you? I'm in Canada, and they are generally next day delivery,
very reasonable shipping charges too. For orders over C$100 shipping is free,
only flat rate of C$8.00 if under C$100. That's for FedEx overnight.
Mouser is also free with a C$100 order, but takes a couple of days. But C$20.00
for orders under C$100.

[Peter W.]

a) Mouser has an UK location.
b) https://www.mouser.co.uk/c/?q=UF5406

A princely 86 P for one. Less per-each for more.

All of this I discovered in less than thirty (30) seconds. Really.

Learned helplessness is a wretched state, similar to passive aggression, but less understandable. However, if Mr. Doom is so benighted as to be unable to manage from here, all I need is his postal address - I will make the arrangements with Mouser UK for its delivery. Gratis.

No it does not. That is just a portal into its US warehouse in Texas.
That's why it gets really busy and the ping latency becomes insanely
long around the same time that Silicon Valley wakes up.

Now you've already been exposed as a troll, so kindly fuck off. Thank
you.
