I have a lot of diodes from china in small bags.
On a bag it handwritten 4v7 for example.
Inside that there are diodes with:
5A3
5T
Does this mean the diode is 5.3 volt instead of 4.7?
And the 5T keeps coming back, what is that?

No, it's a 4,7V zener diode. Did you Google it? Gives you a nice document: http://www.excel-semi.com/pic/Catalog.pdf
Not sure what 5T is but my guess is a data code.

I did use google but it didn't really help.
I saw explanations about first symbol and second symbol but it didn't match.
How do you use that catalog from the pdf in your post?
If I search for 5A3 it is listed in a column that tells me to go to page 16.
On page 16, I can find the 4.7 volt value but I have no clue how it relates.
Page 16, column 1, first number, second column, last part. So column 1: 5, column 2: A3 => 4,7V.
I was looking at page 16 of the pdf instead of the page numbered page 16...
I was really tired yesterday... thx!
Hehe
