I think there is some binning going on, but that is not all.
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. There are applications which require more precision though. These devices are widely used and recommended for general-purpose use, e.
There appears to be two fundamentally different types of diodes sold as ratasheet What is the difference between 1N and 1N other than their maximum reverse voltage?
The 1Nx or 1N or 1N  series is a family of popular 1 A general-purpose silicon rectifier diodes commonly used in AC adapters for common household appliances. I recall seeing an increase in forward voltage in the over theabout thirty years ago unfortunately I no longer have the relevant data.
According the manufacturer specifications, the forward voltage drop is totally equal for all 1Nx diodes. If you are planning to use them for something more sensitive, you might want datzsheet test them all to see which one suites better.

Home Questions Tags Users Unanswered. Can you provide any reference for your answer? Due to daasheet variations, manufactured semiconductor devices may have different characteristics. They also have lower junction capacitance at all reverse bias voltages eg. In these applications you might want to be able to choose a suitable breakdown voltage.
1Nx datasheet & applicatoin notes – Datasheet Archive
Even if I’m right about this manufacturer, the number of pools can be manufacturer specific. PN diodes can be much more complex than a simple 2D model demonstrated in all the theoretical examples The series was second sourced by many manufacturers.
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.
So, why would one produce 1N Diodes with higher reverse voltage ratings are intentionally manufactured with lighter doping so that the depletion region for a 1n40x0 reverse voltage is wider than it otherwise would be. The 1n diodes are a lot bulkier than 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 different versions spec’d in, so each MFR keeps offering every version.
Retrieved from ” https: 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.
Spehro Pefhany k 4 Its blocking voltage varies from 50 volts 1N to volts 1N I’m completely datsaheet that binning strategy is employed for 1Nx, but I can’t say how many pools were initially produced.
After sorting they are marked respectively. For actual curves illustrating the difference, refer to the Motorola Semiconductor Library databooks.

I sure 1n40x0 the answer from Spehro Pefhany, but in today’s datasheets- many do not mention any differences anymore Once they do this they can sell the better performing dtasheet for more money. 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. From Wikipedia, the free encyclopedia. I compared 1Nx diodes here. Views Read Edit View history.
The following table lists part numbers in the 1Nx, 1Nx, and other popular general-purpose silicon rectifier diode families. Thank you for your interest in this question. The first type is a conventional diode and is sold as 1N
