The 1Nx series is a family of popular 1 A general-purpose silicon rectifier diodes commonly Though some writers and datasheets refer to “1N series “, a 1N is a watt Zener diode unrelated to the 1N series of 1 ampere . 1K/Bulk. 1NT.

As far as I see, all of their properties are same other than their maximum reverse voltages. Spehro Pefhany k 4 Retrieved February 27, The series was second sourced by many manufacturers. It looks like 1N is the super version of all other 1Nx diodes.
Archived PDF from the original on February 27, Views Read Edit View history. I think there is some binning going on, but that is not all.
I’m completely sure that binning strategy is employed for 1Nx, but I can’t say how many pools were initially produced.
In these applications you might want to be able to choose a suitable breakdown voltage. I compared 1Nx diodes here. I can hardly believe that diode’s manufacturers just throw away poorly performing diodes and do not try to sell them as a less tolerant device. 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.
Untitled periodical Use dmy dates from April The semiconductor technology is not so precise, so, the diodes, produced in one technological cycle are different.
People say that there are also applications which take advantage of diodes’ reverse breakdown. Its blocking voltage varies from 50 volts 1N to volts 1N It is possible that manufacture has changed and this is no longer true; I can’t see any current evidence for it. Archived from the original PDF on February 23, What is the difference between 1N and 1N other than their maximum reverse voltage?
For actual curves illustrating the difference, refer to the Motorola Semiconductor Library dataxheet. In modern times we would likely use a different type of diode at higher frequencies over a few kHz square wave ddatasheet maybe 5kHz sine wave so the differences are no longer that important, but a few folks have pushed the PIN types into RF service.
My guess is that years ago, when these diodes were just introduced and the semiconductor processes were not mature, the differences between different diodes were more pronounce.

The 1n diodes are a lot bulkier datasheeet the 1n if I remember correctly These diodes are typically available in the larger DOAD axial package to dissipate heat better. Seems there is no perceivable difference anymore, other than many BOM’s have 1n40x versions spec’d in, so each MFR keeps offering every version.

According the manufacturer specifications, the forward voltage drop is totally equal for all 1Nx diodes. So, you can 1h400x a 1N 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. Their maximum current recovery time reverse leakage current capacitance are the same.
This guess is based on the fact that the data for Typical Junction Capacitance in the datasheet has two regions.
1N400x general-purpose diodes
A good generic diode for 1 A or less is the 1N series devices. 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. If the price is the same and you use these datashee in “standard” applications like low frequency rectificationyou may use any of them datashet long as it satisfies your requirements for reverse breakdown voltage.
There are many more parameters which differ; part of the differences are mentioned in the datasheet like the aforementioned junction capacitanceothers are not.
After sorting they are marked respectively. There appears to be two fundamentally different types of diodes sold as 1N From Wikipedia, the free encyclopedia. Common diodes are the 1N, for light-duty signal-switching applications, and the 1N series 1N, 1N, 1N, and 1N It is a common practice not only for diodes.
This page was last edited on 5 Julyat To my best knowledge, junction capacitance is very sensitive to depletion layer width. If 1N does the job alone, then why are the other versions still in the market?
Once they do this they can sell the better performing devices for more money.
