So, why would one produce 1N The robot builder’s bonanza 2nd ed. The 1n diodes are a lot bulkier than the 1n if I remember correctly I sure like the answer from Spehro Pefhany, dataaheet in today’s datasheets- many do not mention any differences anymore By using this site, you agree to the Terms of Use and Privacy Policy.

1N400x general-purpose diodes

I think there is some binning going on, but that is not all. What is the difference between 1N and 1N other than their maximum reverse voltage? There appears to be two fundamentally different types of diodes sold as 1N PN diodes can be much more complex than a simple 2D model demonstrated in all the theoretical examples Would you like to answer one of these unanswered questions instead?

Due to process variations, manufactured semiconductor devices may have different characteristics. According the manufacturer specifications, the forward voltage drop is totally equal for all 1Nx diodes.

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. I don’t know the specifics though. These properties must affect almost any electrical parameter of the diode. It is possible that manufacture has changed and this is no longer true; I can’t see any current evidence for it.

One has to wonder if some parts are not even binned dataheet days, but merely labelled as demand dictates, and propagated simply because they are foundational parts that will probably never go obsolete.

The difference between these diodes is mainly their reverse breakdown voltage.

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. Retrieved from ” https: 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.

There are many more parameters which differ; part of the differences are mentioned in the datasheet like the aforementioned junction capacitanceothers are not. These all are the same diode. They also have lower junction capacitance at all reverse bias voltages eg. Even if I’m right about this manufacturer, the number of pools can be manufacturer specific.

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. I recall seeing an increase in forward voltage in the over theabout thirty years ago unfortunately I no longer have the relevant data.

But they are all 8pF in the new 1NxG versions In general, x20 ratio in reverse breakdown voltages between 1N and 1N reflects major differences in junctions’ properties. My guess is 2 pools, from which 7 bins were derived.


Thank you for your interest in this question. These devices are widely used and recommended for general-purpose use, e. To my best knowledge, junction capacitance is very sensitive to depletion layer width. Vasiliy 6, 2 14 It is datasheef common practice not only for diodes. If 1N does the job alone, then why are the other versions still in the market?

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

Once they do this they can sell the better performing devices for more money. A good generic diode for 1 A or less is the 1N series devices. The series was second sourced by many manufacturers. I’m completely sure that binning strategy is employed for 1Nx, but I can’t say how many pools were initially produced. Retrieved February 22, In these applications you might want to be able to choose a suitable breakdown voltage.

After sorting they are marked respectively. This guess is based on the fact that the data for Typical Junction Capacitance in the datasheet has two regions. This page was last edited on 5 Julyat There are applications which require more precision though.

From Wikipedia, the free encyclopedia. These diodes are typically available in the larger DOAD axial package to dissipate heat better. Retrieved February 27, Archived from the original PDF on February 23, Can you provide any reference for your answer? Its blocking voltage varies from 50 volts 1N to volts 1N
