Akbo to find one .... is it normal for me to measure .279 these diodes? .... usually they should measure .400 upwards ... or they measure like this ... someone who takes away my doubts ... please .... I'm out of date ... please ...

I am going to give you some advice because you ask things that are not usually answered in the forums, they usually take you as a nobato, look for how to check ultra-fast diodes in a search engine and you will see that you are careful to find these videos in Spanish and not only for diodes

I am an apprentice in a workshop, only that the teacher lends us his coputadoray and is the only one in the workshop for us to ask and how he has his account .... he says that when one strives he does the work better

I have also been learned and sutodidact and if you know what you do is measure the voltage drop and for normal diodes it is 0.7 in practice somewhat less if it is Schottky between 0.2 and 0.4 and if it is Germanium it is weirder but in a very frequent way you find them 0,150
It is not accurate but if it is not burned around those values if it is burnt out of the circuit or is aviary or is in conto always testing large polarities and all the measurements are not exact if you want something exact look for reference there are many data that the tester does not he gives them to you

I miss you I don't see how to edit if I miss something important you say it but or your teacher that if you ask him well he must answer you what they teach for and it is a question that gives for much other is that I already diet it and you will look the other way if you fuck

If I do not misunderstand you have others if you do in alldatasheet you can look for this Maximum Recurrent Peak Reverse Voltage 200v, Maximum RMS Voltage 140v, Maximum Average Forward Rectified (this is the intention to work on ampios cotinuado up to 10p degrees the most important) 10th, Peak Forward Surge Current, 8.3ms single (this is the intention in non-repetitive peaks too important) 100a, the C / W degrees per watt, Maximum Reverse Recovery Time (Note 1) (this would be the minimum recovery time) 35 ns Depending on the application, there are more critical values than others if it is suspected that it melts due to voltage spikes and I throw at a model with more voltage equal amperage if it is hot and it is more delicate to alter it depends on use even more endurance but it can be caused breakage On the other hand, it fails because of the data you give alldatasheet you have them all and look well the pinout if you wanted references I misunderstood you but that data I do not know that I normally give you these things limit us the sellers at least in my area there is no all

There is another way that I had not realized to make a replacement of these diodes that I do not recommend but it works and it is the one that I think you wanted from the beginning if it is a recycled diode as an example atx sources or similar seeks to work the same voltage stages and in case of doubt at more amps than what you intend to replace unless you work twice anyway http://www.alldatasheet.com/ I recommend it because it is rare that you do not give with the data of any component if you know Search and you will not mow.
These are fudge methods but having some data can work.
