doesn't seem to be a
thing that part numbers of modern switching diodes routinely control.
The bright side is that they're common as dirt and about as cheap, so if
you're willing to invest some time and effort getting intimate with a
multimeter, you can buy a thousand of them and bin them for voltage drop
yourself. 1N914/4148 (to my knowledge, they're basically identical) is
usually specified for "I need a diode and don't expect to blow it up",
so the characteristics aren't usually all that tightly controlled.
The only problem with that plan is that a given manufacturer, and
especially a given lot, will likely have nearly identical characteristics.
One could, however potentially discover that some lots of Fairchild
1N914 are more like D664, while Vishay are always more like D662,
etc.
