The 1Nx or 1N or 1N  series is a family of n1400x 1 A general-purpose silicon rectifier diodes commonly used in AC adapters for common household appliances. This guess is based on the fact that the data for Typical Junction Capacitance in the datasheet has two regions.
In 1n4000x times we would likely use a different type of diode at higher frequencies over a few kHz square wave or maybe 5kHz sine wave so the differences are no longer that important, but a few folks have pushed the PIN types into RF service.
The difference between these diodes is mainly their reverse breakdown voltage. This page was last edited on 5 Julyat The 1n diodes are a lot bulkier than the 1n if I remember correctly According the manufacturer specifications, the forward voltage drop is totally equal for all 1Nx diodes.
The disadvantage with lighter doping is that the forward resistance datwsheet voltage drop for a high-voltage diode is higher than it would be for a lower-voltage diode.
As far as I see, all of their properties are same other than 1n040x maximum reverse voltages. So, you can use a daatsheet for all of your applications, but your circuit efficiency will be slightly higher if you use a more appropriately-rated diode in low-voltage applications.
If 1N does the job alone, then why are the other versions still in the market? They also have lower junction capacitance at all reverse bias voltages eg. It is possible that manufacture has changed and this is no longer true; I can’t see any current evidence for it.

Spehro Pefhany k 4 Common diodes are the 1N, for light-duty signal-switching applications, and datxsheet 1N series 1N, 1N, 1N, and 1N Retrieved February 22, The semiconductor technology is not so precise, so, the diodes, produced in one technological cycle are different. A good generic diode for dattasheet A or less is the 1N series devices. There are dataheet which require more datasneet though. Diodes with higher reverse voltage ratings are intentionally manufactured with lighter doping so that the depletion region for a given reverse voltage is wider than it otherwise would be.
These devices are widely used and recommended for general-purpose use, e. Untitled periodical Use dmy dates from April Even if I’m right about this manufacturer, the number of pools can be manufacturer specific. Views Read Edit View history. I recall seeing an increase in forward voltage in the over theabout thirty years ago unfortunately I no longer have the relevant data. I sure like the answer from 1n00x Pefhany, but in today’s datasheets- many do not mention any differences anymore In general, x20 ratio in reverse breakdown voltages between 1N and 1N reflects major differences in junctions’ properties.
Manufacturers tend to represent these diodes as having exactly the same properties because the very fine differences are not important for main areas of employment of these diodes. There appears to be two fundamentally different types of diodes sold as 1N Once they do datasheer they can sell the better performing devices for more money. I don’t know the specifics though. After sorting they are marked respectively. From Wikipedia, the free encyclopedia.
I think there is some binning going on, but that is not all.
I compared 1Nx diodes here. My guess is that years ago, when these diodes were just introduced and the semiconductor processes were not mature, 1n400z differences between different diodes were more pronounce.
These all are the same diode. These properties must affect almost any electrical parameter of the diode.
Archived PDF from the original on February 23, The first type is a conventional diode and is sold as 1N I can hardly believe that diode’s manufacturers just throw away poorly performing diodes and do not try to sell them as a dqtasheet tolerant device. Due to process variations, manufactured semiconductor devices may have different characteristics.
