There appears to be two fundamentally different types of diodes sold as 1N So, why would one produce 1N 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 diode. Common diodes are the 1N, for light-duty 1n400c applications, and the 1N series 1N, 1N, 1N, and 1N Retrieved February 27, There is no disadvantage except possibly price in using 1N diodes for everything.

People say that there are also applications which take advantage of diodes’ reverse breakdown. There are applications which require more precision though. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

It looks like 1N is the super version of all other 1Nx diodes. 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. The semiconductor technology is not so precise, so, the diodes, xatasheet in one technological cycle are different.

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. The answers by Vasiliy and johnfound are incorrect.


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. Archived PDF from the original on February 27, I recall seeing an increase in forward voltage in the over theabout thirty years ago unfortunately I no longer have the relevant data.

From Wikipedia, the free encyclopedia. But they are all 8pF in the new 1NxG versions This page was last edited on 5 Julyat The series was second sourced by many manufacturers. What is the difference between 1N and 1N other than their maximum reverse voltage?

Oh no, there’s been an error

These all are 1n400z same diode. I don’t know the specifics though. There are many more parameters which differ; part of the differences are mentioned in the datasheet like the aforementioned junction capacitance1n040x are not.

Archived from the original PDF on February 23, Vasiliy 6, 2 14 For actual curves illustrating the difference, refer to the Motorola Semiconductor Library databooks. 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 Datasyeet types into RF service.

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.

I compared 1Nx diodes here.

So, you can use a 1N for all of your applications, but your circuit efficiency will be slightly higher if you use a dagasheet appropriately-rated diode in low-voltage applications. Its blocking voltage varies from 50 volts 1N to volts 1N 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.


According the manufacturer specifications, the forward voltage drop is totally equal for all 1Nx diodes. The robot builder’s bonanza 2nd ed. The difference between these diodes is mainly their reverse breakdown voltage. Archived PDF from the original on February 23, 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. Can you provide any reference for your answer?

Would you like to answer one of these unanswered questions instead? My guess is 2 pools, from which 7 bins were derived. This guess is based on the fact that the data for Typical Junction Capacitance in the datasheet has two regions. If 1N does the job alone, then why are the other versions still in the market?

Even if I’m right about this manufacturer, the number of pools can be manufacturer specific. The first type is a conventional diode and is sold as 1N These properties must affect almost any electrical parameter of the diode.

Additionally, sometimes not very dagasheet there are schematics where the diode works in avalanche breakdown mode, so you will need the breakdown voltage to be predictable.

Retrieved February 22, Spehro Pefhany k 4 I think there is some binning going on, but that is not all. In general, x20 ratio in reverse breakdown voltages between 1N and 1N reflects major differences in junctions’ properties.
