Hard to decipher some semiconductor part numbers, these days.

1N, 2N, 3N devices are well defined but 4N and 5N and 6N parts were never?
defined. Does anybody out there actually know if the old JEDEC standard was
dropped, or usurped, or has it just faded into the past? I cannot find a
JEDEC reference to a 6Nxxx optocoupler.

The JEDEC standard worked to some extent. I think perhaps I need more than
you can provide, dear GOD

It appears from your numerous recent postings that you need to learn
something about how Usenet (that's where you've posted these messages)
works.

You've posted the same question now in at least three threads in this
newsgroup with no apparent luck so far, apart from drawing some abuse
from Phil Allison. (A word about Phil: while he can be an absolute ass,
especially when he is apparently off his meds, he is also quite
knowledgable about things electronic.)

You might want to think about rephrasing your question: what is it you
want to know, anyhow? I think Phil is right: the JEDEC standard, at
least the 2Nxxxx one, is demonstrably NOT uniform, orthogonal,
standardized, as he demonstrated. Now, if you just want to complain or
rant about this lack of usefulness in this "standard", you are of course
welcome to do so here; just realize that you probably won't get much in
the way of useful feedback if you do.

On the other hand, if you're trying to track down some specific part #s,
then why don't you just say so?

I believe the initial number is the number of PN junctions in the device --
at least as far as junction devices go.

** How many junctions does a 2N5459 j-fet have ?

Technically, one. JFETs are not generally considered "junction" transistors,
though they contain a junction. That's why I phrased my remark as I did.

The type designations are controlled by the JEDEC under document
JESD270B which tracks ANSI/EIA-370-B-1992. You can get a copy at:
<http://www.jedec.org/standards-documents/docs/jesd-370b>
but you'll need to register and login.

Section 1a mumbles something about the first digit, minus 1, equals
the number of useful electrical connections (which do not include the
case shield connection).

** Fits nicely with 3Nxxx numbers being all dual gate mosfets.

So, if your device has a half dozen
electrical connections, it would be a 5Nxxxx.

** Dunno if JEDEC numbers really cover ICs at all.

Imagine an SMD uP being a " 99Nxxxxx "

Is the 4Nxx series of optos JEDEC registered ??

You and Phil and Mike need to learn about basic civil behavior. The first
and second posts garnered rude and irrelevant replies. So, I re-posted ...
Shame On Me! I think questions are healthy and interesting things and help
us all advance. I think stupid and rude responses are beyond the pale.
