2N7000
Why is this article marked for merging with MOSFET yet the similar part BS170 is marked for merge with Transistor? —Preceding unsigned comment added by 64.139.9.139 (talk) 01:02, 9 November 2009 (UTC)

I want to hear more history on how this part came to be, it is so famous. Who registered the JEDEC number first, and how did they manage to get 7000?192.80.95.243 (talk) 17:23, 29 September 2010 (UTC)

Related parts
Why is Mr. W still spreading his negativity, removing sourced information about related parts? If the title is too narrow, there are more constructive ways to address that. Dicklyon (talk) 01:20, 17 April 2011 (UTC)
 * Checking - it's dead simple to cut'n'paste a user name such as "Dicklyon ". This article says it's about the 2N7000. It seems to me then, that this article cannot be about 1N4148, 1N4001, and 1N4007 switching and rectifier diodes, and  2N2222, 2N3904, and 2N3906 bipolar transistors. Could someone please tell me what the common link is, other than all being in someone's parts bin? How are these parts related?  I suppose they are all made from silicon - is that the peg?  How then do we exclude the 555 timer? I honestly don't understand why this parts list entry needs to refer to a random selection of other parts that are unrelated.  I suppose we could have "Popular Semiconductors" as an article title but that seems poorly defined - we still don't know, for example, when the 2N7000 was registered or by what company, and we still don't know if they sell 3000, 3000000 or 300000000 a year. --Wtshymanski (talk) 13:48, 17 April 2011 (UTC)
 * The 1991 ARRL Handbook, chapter 35, lists 11 pages of popular semiconductors (not counting the IC pages). How do we decide which ones get listed in this article? --Wtshymanski (talk) 15:14, 17 April 2011 (UTC)
 * Why are you being such a pain? Can't you see the sources that show the described relationships of the 2N7000 to the other parts mentioned?  If you're against articles on individual parts, how is that agenda advanced by picking on articles that talk about multiple related parts?  Can't you find something constructive to work on?  Dicklyon (talk) 15:32, 17 April 2011 (UTC)
 * What is this article about? This is the Wikipedia, where you get barnstars for taking "poo" out of articles, if you do enough of it.  I wouldn't get too deeply into discussing the "constructiveness" of any set of edits. I would like to see articles to be about their subjects, and not coat racks to contain lists of the parts we remember from our lost youth. Perhaps I have an unimaginative and restricted definition of "related parts", less inclusive than the writer of the "Dummies" book. Why aren't we also listing red and green LEDs, the 7812 voltage regulator, and the IRF 510 FET here, too? There must be a more accessible definition of "related parts" other than "what J. Random Wikieditor thinks is related". --Wtshymanski (talk) 17:29, 17 April 2011 (UTC)
 * It's about the 2N7000 low-power MOSFET and closely related parts. Is it OK if it also mentions other parts that certain sources mention in the same sentence with it, or is this just too much like poo for you?  Dicklyon (talk) 18:52, 17 April 2011 (UTC)

Suggest move merge
Since we want to talk about the wide world of power MOSFETs here, perhaps we should rename the article "Power MOSFETs" or something less particular? Seems silly to spend most of the article talking about other parts or about the general properties of power MOSFETs that don't pertain to this particular parts list entry. --Wtshymanski (talk) 17:36, 17 April 2011 (UTC)
 * And it seems we have an article Power MOSFET - let's merge this parts catalog with that under "Popular devices"! --Wtshymanski (talk) 17:39, 17 April 2011 (UTC)

It seems like a bad fit to merge these small switches into a power article. Does anyone even refer to them as "power MOSFETs"? I removed the merge proposals as too lame to invite editors to waste time on. Dicklyon (talk) 18:21, 17 April 2011 (UTC)

Now that you've restored the merge proposal, can you tell us why? Did you google "2N7000" and "Power" and find something interesting? Or just the ones that say "low-power"? Did you look at the Power MOSFET article to see what it says, and whether there's any suggestion of a fit there, like where it says "designed to handle significant power levels"? Does "significant" here mean less than a watt? Let us know. Dicklyon (talk) 18:49, 17 April 2011 (UTC)

diode from source to drain
Usually there is a diode drawn from source to drain in schematics. I think that makes it different from other mosfets. I can see there is a note in the infobox but I would prefer to see it in the picture. --Jx (talk) 07:37, 19 April 2017 (UTC)


 * That's no different from other MOSFETs. The diode isn't added deliberately as a design feature, it just comes about as an artefact of the manufacturing process. As it's reverse biased, it's usually ignored. It may have some usefulness at times, its presence might require consideration for high frequencies. Andy Dingley (talk) 08:51, 19 April 2017 (UTC)
 * And it's not from source to drain – it's from source to bulk (channel); also from drain to bulk, though not usually shown; alternatively, think of it as, and often drawn as, diode from channel to bulk (e.g. from N channel to P bulk or vice versa). The bulk terminal is sometimes hardwired to source in discretes (like the 2N7000), or sometimes (like on an IC) is tied to ground or a substrate bias potential, to keep this diode off.  The arrow on the transistor schematic is mostly there as one way to indicate P vs N channel.  On the other hand, if you see a diode drawn from source to drain, that might be a separate "free-wheeling" diode, to pass an inductive kickback or reflection after the transistor shuts off. Dicklyon (talk) 15:15, 19 April 2017 (UTC)
 * What the infobox says is confusing. I think it's referring to the source/drain/channel-to-bulk diode shown, which is sometimes not shown.  It's not said well. Dicklyon (talk) 15:21, 19 April 2017 (UTC)
 * I editted the comment. OK?  Dicklyon (talk) 02:36, 21 April 2017 (UTC)

Attention. Grouping 2N7000 and BS170 is dangerous. Although these parts are similar N-channel MOSFETs with slightly different current characteristics, they have DIFFERENT pinouts. Source and Drain are reversed in the TO92 package.

2N7002
This article erroneously states that the 2N7002 differs only in package and that the electrical specifications are identical to the 2N7000. This is clearly wrong, given even a cursory glance at the current Onsemi datasheet. They are close, but differ in gate threshold voltages, collector current limitations, power dissipation, Idss, etc. — Preceding unsigned comment added by 47.185.80.140 (talk) 15:43, 14 June 2023 (UTC)
