content: I'm looking for a chart/table/listing, whatever you want to call it, that shows all diodes (or as many as possible) listed in part # order, across all types (rectifier, signal, Schottky, zener, etc.). Does anyone know of such a resource online?I have an old copy of the ARRLHandbook(1991) which has some tables in the back, but it's far from complete, and the largest section, zeners, has them listed in voltage/power order, with the part #s all over the place.Thanks in advance to any help here.

content: Mouser EU lists about 188000 diode items in its most generic search. Selecting "in stock" filter reduces this list to about 47000 items. It would help if you clarified a bit more the intended goal of such endeavor.

content: Thanks, but that doesn't look helpful at all.I'm trying to sort a bunch of unknown diodes I have.I need a listing that's sorted by part number, if such a thing exists.

content: Quote from: Analog Kid on June 23, 2025, 08:19:51 pmAs an absolute statement, it’s unlikely any such resource exists, or even could exist. Something might exist that has _most_ parts and lists _most_ characteristics, but nothing will have _every_diode and _every_ parameter, never mind in a manner that makes them directly comparable. (If you want to see what I mean, just do what I attempted some months ago and try to figure out the exact differences between the 1N914, 1N916, 1N4144, and 1N4148 diodes, especially if considering the differences between the no-suffix, A, and B versions. See the attached datasheet.)

content: Quote from: Analog Kid on June 23, 2025, 09:46:41 pmI intended to show you the scope of what you are looking for, given the little details of what you intended to do.Quote from: Analog Kid on June 23, 2025, 09:46:41 pmNow that you clarified the goal, I can suggest that you could filter down that search by "mounting style" and "package/case". For example, limiting the query to "through hole" reduces the item count from 188000 to about 7200. As a further example, additionally limiting the query by the "package/case" to "TO-220" and its variants reduces the item count to about 1200.Mouser search is sortable by part number, if you wish.

content: Quote from: tooki on June 23, 2025, 10:49:23 pmYou're probably right. However, I don't really need many characteristics apart from what type (rectifier, signal, zener, etc.) it is and maybe just voltage and power ratings. A listing that listedmostparts available would be most welcome.

content: Quote from: Analog Kid on June 23, 2025, 11:43:46 pmYou mentioned you were trying to sort a bunch of unknown diodes. How would a static list of diodes (like from a printed databook) would help with this case? Do you intend to compare the pictures of each one with what you have? This may not help in many cases since diodes with different parameters share the same form factor.It would be much faster to test each one with a "transistor tester" type of device and then do an online lookup based on its shape and the information the tester device gives.This is the thread for the transistor tester device I am talking about:https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/

content: There used to be a JEDEC 'Diode / SCR / Thyristor Data book. The index was by part number which then referred to the page the data was on. Sadly, I tossed mine years ago. Probably could still find a copy on Ebay.

content: 1) If you have a part #, virtually any online list you can find will allow Windows to search by the part number, i.e., ctrl+f then part #2) If you have a part number, any search engine can take you to its datasheet3) If you don't have a part number, what help would a listing of the many thousands of diodes that have been made be? You are screwed.

That was my first question.And thank you very much, but I think I've figured out how to search text after 50 years of using computahs.QuoteWell, I guess that's my fallback position, isn't it.

content: Quote from: Analog Kid on June 23, 2025, 09:46:41 pmManually looking through a list is a bit old-hat.Just open Mouser or Digikey's website, key in the part number, and you'll get the basic description in a consistent web page formatwithouteven having to look at a datasheet.If I key in 1N4004 it shows me several part options that all say standard 400V 1A diode. Job done, key in the next part number. 1N750, 4.7V Zener 0.5W. Next!

content: Quote from: Analog Kid on June 24, 2025, 01:05:16 amMore than 10 years ago I wanted to make such list of available DCDC ICs.At Digikey.com when selected such ICs I was able to download the whole list in a spreadsheet form (or may be page by page - don't remember).Then when you have it in your spreadsheet you can manipulate it as you want including sorting.Also at digikey when you have a table with selected devices by clicking in column title you can sort items by this column. May be it will be enough for you.

content: Also, if you ever come across "short form" datasheets while searching documentation for a part, these often are data book page scans that list lots of parts per page. This is the closest thing to what you're looking for I can think of.

content: I have some amount of paper books an datasheets saved on disk but found it is nowadays much faster to just google "part-number pdf" than start a search in my own datasheet catalog on my disk. Googling is (sometimes much) faster than both paper book searching and looking into my previously saved files.So, I guess Internet + google is what TS really need.

Everything you don't like you assume is "trolling", eh?My motive was to find such a resource if it existed.Apparently it doesn't, so my recourse is to do online searches.Fortunately I don't have all that many devices to look up.As Steve Martin said, Excuuuuuuse me for asking the question.

content: Quote from: Analog Kid on June 24, 2025, 12:54:14 amThere you go.The 1N are standardized, made by probably a hundred different companies.Hack the 1N number into google, there are plenty of datasheets available.And yes, the 1N has it all - so you really need to look it up. One thing I noticed: Special Zeners do come in unusual colors (at least my older parts did - not sure if that changed).

content: Quote from: Haenk on June 27, 2025, 09:27:41 amIn a first-order sort I found thatmost--but by no means all--of the little glass diodes were zeners, with the remainder being just small signal (1N4148-ish) and Schottky types.The black jobbies were almost all just plain rectifiers (1N400x, etc.).BTW, this was the result of buying a 200-pc. "grab bag" from Jameco. A party mix of diodes. Mmmm, those pretzels are good ...
