Interesting question.?

There are interesting amateur tests of the 1N4007/1N5408 as replacements for the Unitrode P-I-N characterised diodes. At least one experiment shows that 1N5408's were lower resistance than the purpose designed Unitrodes with one caveat: the recombination time of the 1N5408's/1N4007's is getting skimpy (not long enough) for perfect use at 160M.?

Considering the unknown sourcing issues of modern devices, and the clever re-marking methods, I have no confidence that parts sold with jedec registered numbers will meet specifications, much less undocumented specifications.

Or as one person famously said, "Trust but verify!", which is why I included the links.
