Talk:2N2222

2N2222
PN2222 is not another name for a 2N2222. The 2N2222 comes in a small metal can called a TO18. The PN2222 comes in a plastic TO92 case. The whole purpose of there being a PN2222 is to take advantage of the cheaper encapsulation. The tradeoff is higher thermal resistance. Referencing the respective datasheets would be useful.

Texas Instruments?
Texas Instruments does NOT make the 2N2222. Get your facts right! — Preceding unsigned comment added by Yusiang1998 (talk • contribs) 12:20, 23 December 2011 (UTC)

European equivalents
The venerable BC548 is mentioned as a substitute, commonly found in electronics parts boxes. Many of the parameters, most notably Ic fall short. The more modern and closer European equivalent is the BC337. A BC337-40 would perform at least as well as the 2N2222 in applications where Vcb won't exceed 50v.

Stub
Should this article still be a stub? It seems that it now has quite a bit of content, and I always though stubs were articles that were only a few sentences long. There are some other articles of a similar lenght that aren't marked as stubs.

format ok?
I don't know the format issues, but the page certainly told me what I came here to find out... —Preceding unsigned comment added by 216.184.13.6 (talk) 15:30, 14 June 2009 (UTC)

"often referred to as the 'quad two' transistor" ... although I have used this item for the past 35+ years, I have never heard one person refer to it as a "quad two" transistor. No one in engineering school, no one at various places of employment. This isn't relevant enough or important enough of an anecdote to insert into an otherwise informative page. —Preceding unsigned comment added by Zapriori (talk • contribs) 07:42, 17 November 2009 (UTC)

Deleting?
This article is not only talking about this transistor as a part, but it does contain information about the history of the transistor. This transistor is widely use for a long time and it should not be delete. — Preceding unsigned comment added by Geologie (talk • contribs) 23:13, 24 March 2011 (UTC)

 * Seems to have been the subject of a nuclear EMP study: "Nuclear EMP: failure threshold and resistance of the protected and unprotected 2N2222 transistor in the short pulse width regime"
 * Lots of hits for blog entries so seems popular
 * Lots of groups hits, so a popular topic of discussion
 * Seems to have been the subject of a breakdown study:
 * Seems to have been a transistor studied with other transistors, with the effect on them in various conditions
 * Seems to be used as an exemplar of standard transistors of its characteristics
 * A "D.C. Wunsch" seems to have done damage studies on it, that cited by others

Was most useful, I know I'm a meaningless unvalid source, but I find the graph paper and felt pen downright cheerful, and although intangible sensations such as love are utterly lost upon the tenets of an anal attentive entity such as wikipedia, I declare this article as not only valuable, but also worth preservation. 04:30, 23 February 2014 (UTC) — Preceding unsigned comment added by 50.0.75.4 (talk)

JEDEC registry
Fellas, if it's not in a TO 18 case, it's not a JEDEC registered 2N2222. That's kind of the *point* of the number, you order a 2N2222 from DigiKey and you get a device in a metal case with thus-and-so properties, no matter which mysterious Far Eastern fab hammered it together. If it's not about *this* transistor, put it in an article called "Development of silicon transistors". --Wtshymanski (talk) 19:34, 2 April 2011 (UTC)

External links modified
Hello fellow Wikipedians,

I have just added archive links to 1 one external link on 2N2222. Please take a moment to review my edit. If necessary, add after the link to keep me from modifying it. Alternatively, you can add to keep me off the page altogether. I made the following changes:
 * Added archive https://web.archive.org/20090930205649/http://datasheetreference.com:80/2n2222-datasheet.html to http://datasheetreference.com/2n2222-datasheet.html

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Brilliant prose
We used to call "lower current at medium voltage" 30 amps at 4160 volts. Meaningless qualifiers do not serve the reader well. But what can you expect from a parts list entry? --Wtshymanski (talk) 04:03, 7 July 2022 (UTC)
