A good generic diode for 1 A or less is the 1N series devices. 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.

Diode 1N4001

In general, x20 ratio in reverse breakdown voltages between 1N and 1n400s reflects major differences in junctions’ properties. 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.

It is a common practice not only for diodes.

Once they do this they can sell the better performing devices for more money. Even if I’m right about this manufacturer, the number of pools can be manufacturer specific.

As far as I see, all of their properties are same other than their maximum reverse voltages. The difference between these diodes is fatasheet their reverse breakdown voltage. Home Questions Tags Users Unanswered. I don’t know the specifics though. Untitled periodical Use dmy dates from April The series was second sourced by many manufacturers. The first type is a conventional diode and is sold as 1N So, you can use 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.


Spehro Pefhany k 4 This guess is based on the fact that the data for Typical Junction Capacitance in the datasheet has two regions. It looks like 1N is the super version of all other datashdet diodes. I recall seeing an increase in forward voltage in the over theabout thirty years ago unfortunately I darasheet longer have the relevant data.

1N400x general-purpose diodes

According the manufacturer specifications, the forward voltage drop is totally equal for all 1Nx diodes. But they are all 8pF in the new 1NxG versions Retrieved February 27, For actual curves illustrating the difference, refer to the Motorola Semiconductor Library databooks.

The robot builder’s bonanza 2nd ed. In other projects Wikimedia Commons. Thank you for your interest in this question.

1NX Hoja de datos ( Datasheet PDF ) – A RECTIFIER

Manufacturers tend to represent these diodes as having exactly the same datasjeet because the very fine differences are not important for main areas of employment of these diodes. The 1Nx or 1N or 1N [2] series is a family of popular 1 A general-purpose silicon rectifier diodes commonly used in AC adapters for common household appliances.

The 1n diodes are a lot bulkier than the 1n if I remember correctly Archived PDF from the original on February 23, Retrieved February 22, Can you provide any reference for your answer? I think there is some binning going on, but that is not all. Vasiliy 6, 2 14 Views Read Edit View history.


In these applications you might want to be able to choose a suitable breakdown voltage. There are applications which require more precision though. Archived PDF from the original on February 27, The disadvantage with lighter doping is that the forward resistance and voltage drop for a high-voltage diode is higher than it would be for a lower-voltage 1h400x.

1Nx general-purpose diodes – Wikiwand

If you are planning to use them for something more sensitive, you might want to test them all to see which one suites better. PN diodes can be much more complex than datasjeet simple 2D model demonstrated in all the theoretical examples I sure like the answer from Spehro Pefhany, but in today’s datasheets- many do not mention any differences anymore If 1N does the job alone, then why are the other versions still in the market?

These diodes are typically available in the larger DOAD axial package to dissipate heat better. This page was last edited on 5 Julyat
