Seems there is no perceivable difference anymore, other than many BOM’s have different versions spec’d in, so each MFR keeps offering every version. There is no disadvantage except possibly price in using 1N diodes for everything. It is possible that manufacture has changed and this is no longer true; I can’t see any current evidence for it. The difference between these diodes is mainly their reverse breakdown voltage.

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. For actual curves illustrating the difference, refer to the Motorola Semiconductor Library databooks.

It is a common practice not only for diodes. After sorting they are marked respectively. In these applications you might want to be able to choose a suitable breakdown voltage. 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.

If 1N does the job alone, then why are the other versions still in the market? Views Read Edit View history. Its blocking voltage varies from 50 volts 1N to volts 1N Archived PDF from the original on February 23, Retrieved February 27, Retrieved from ” https: If the price is the same and you use these diodes in “standard” applications like low frequency rectificationyou may use any of them as long as it satisfies your requirements for reverse breakdown voltage.


One has to wonder if some parts are not even binned these days, but merely labelled as demand dictates, and propagated simply because they are foundational parts that will probably never go obsolete. Their maximum current recovery time reverse leakage current capacitance are the same.

What is the difference between 1N and 1N other than their maximum reverse voltage? This page was last edited on 5 Julyat Retrieved February 22, Can you provide any reference for your answer?

The answers by Vasiliy and johnfound are incorrect.

A good generic diode for 1 A or less is the 1N series devices. There appears to be two fundamentally different types of diodes sold as 1N 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.

Vasiliy 6, 2 14 I sure like the answer from Spehro Pefhany, but in today’s datasheets- many do not mention any differences anymore Archived PDF from the original on February 27, I think there is some binning going on, but that is not all.

These properties must affect almost any electrical parameter of the diode. There are applications which require more precision though. From Wikipedia, the free encyclopedia. Spehro Pefhany k 4 Common diodes are the 1N, for light-duty signal-switching applications, and the 1N series 1N, 1N, 1N, and 1N Manufacturers tend datadheet 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.

This guess is based on the fact that the data for Typical Junction Capacitance in the datasheet has two regions.


Oh no, there’s been an error

According the manufacturer specifications, the forward voltage drop is totally equal for all 1Nx diodes. In modern 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 datashheet into RF service.

They also have lower junction capacitance at all reverse bias voltages eg. These all are the same diode. Would you like to answer one of these unanswered questions instead? Untitled periodical Use dmy dates from April Many manufacturers employ ” binning ” strategy for manufactured parts: Archived from the original PDF on February 23, The first type is a 1b400x diode and is sold as 1N In other projects Wikimedia Commons.

The series was second sourced by many manufacturers. But they are all 8pF in the new 1NxG versions The following table lists part numbers in the 1Nx, 1Nx, and other popular general-purpose silicon rectifier diode families.

People say that there are also applications which take advantage of diodes’ reverse breakdown. I’m completely sure that binning strategy is employed for 1Nx, but I can’t say how many pools were initially produced.
