Expansion needed[edit]

Could we get some facts about this diode that don't come from the DigiKey catalog? How many get made in a year? Why is tehre a 1N4148 when there was already a 1N914? Etc. You know, encyclopedia stuff. --Wtshymanski (talk) 19:17, 2 April 2011 (UTC)[reply]

If you spent less time ranting at other editors for their failings, you'd have time to add this yourself.

Obviously these editors have been very busy the last three years, explaining the omission of this article from FA. The AfD argument says this part is notable and a topic. It's not me that believes this, where are the diode partisans? --Wtshymanski (talk) 20:58, 2 April 2011 (UTC)[reply]
Zzzz..... --Wtshymanski (talk) 18:08, 25 April 2011 (UTC)[reply]

If we take the tags off, that should mean the article has gotten better. It hasn't. Aside from my usual questions as to why we should note any random semiconductor, a non-technical reader might be puzzled by the following mysteries:

  • What's a "high" frequency in this context?
I think I addressed this in the article. --  :- ) Don 21:28, 25 September 2012 (UTC)[reply]
  • Why is there a 1N914 and a 1N4148 if they are the same device? Surely the point of JEDEC numbers is standardization, why make two devices with different numbers if they are the same?
  • What's a "reverse recovery time"? Why is it important?
Wiki-linked --  :- ) Don 21:36, 25 September 2012 (UTC)[reply]
  • What are all those numbers and why are they important?
  • Why is the "average rectified current" different from the "DC forward current" ?
  • Are these numbers exceptionally large/small/good/bad for this class of device?
  • How does this device compare with other part numbers, for example, the 1N4001 so beloved of AfD participants?
  • How is a diode a switch?
  • What sorts of things use this diode? Why? What is only possible because this diode exists?
See: "See also" in the article for the balance of your questions --  :- ) Don 21:36, 25 September 2012 (UTC)[reply]

And so on. Get your friendly local 12-year-old to read this and see if he or she can figure out what this article is supposed to teach. --Wtshymanski (talk) 22:15, 25 April 2011 (UTC)[reply]

  • The 1N4148 and 1N914 are not the same. The reverse current of the 1N4148 is much lower that is why it replaced the 1N914. The 1N914 is speced at 5 microamps reverse current, the 1N4148 25 nanoamps. Other than that, they are basically identical. The reverse recovery time of both is 4 nanosecond, not very fast these days. --  :- ) Don 02:51, 11 August 2012 (UTC)[reply]
Changed characteristics to dependable. I just lost 2 weeks troubleshooting switching regulator because Linear Tech said to use 1N4148 in a reference circuit. I thought how boring, so I use super diode laying around. Well circuit required 600 mv drop to work, and my diodes was only 400 mv. --  :- ) Don 18:42, 26 August 2012 (UTC)[reply]

Notability[edit]

A particular part number is not notable. There's no sources that can be cited to explain anything about this device, other than the parts catalog specifications we already see here. This topic should not exist in the encyclopedia. --Wtshymanski (talk) 13:37, 5 April 2011 (UTC)[reply]

Then why not submit it to AfD? Oh, you did. Then try reading WP:CONSENSUS. Andy Dingley (talk) 15:17, 5 April 2011 (UTC)[reply]
Informed consensus? That would be nice. --Wtshymanski (talk) 19:33, 5 April 2011 (UTC)[reply]

As an electronic technician and hobbyist, I find it extremely useful to be able to come to WP and find all my basic component technical data in one place. I would guess that millions of others feel the same way. Darkman101 (talk) 00:15, 27 December 2012 (UTC)[reply]

From my experience the 4148 is the most used diode in electronic circuits.MadCowpoke (talk) 06:32, 28 December 2012 (UTC)[reply]

There is an assertion of notability is in the article:

"These device types have an enduring popularity in low-current applications.[1]"

It has a reference that describes it as "venerable". For a diode that is pretty good. Chillum 18:15, 28 October 2014 (UTC)[reply]

I just noticed this discussion was over 2 years ago... Chillum 18:17, 28 October 2014 (UTC)[reply]

too much "JEDEC registration" talk![edit]

Article says "JEDEC" 5 times and "registered" 3 times...I don't think the average reader wants to hear about it's JEDEC registration so much, lol. Maybe can someone combine those into like one or two mentions at the most. — Preceding unsigned comment added by Em3rgent0rdr (talk • contribs) 23:55, 30 March 2022 (UTC)[reply]
