Dubious quality but cheap
These are a mixed bag. Sure you get a lot, but I found some to be dead straight from the bag. Not sure they are genuine Sharp.

Works frine
These are working fine in some sensors that I made.

Protection
Needed an optocoupler for a sensitive circuit. Decided to go all in and stock my electronics kit. I've only used two of them, but both worked flawlessly.

Tested the current transfer ratio, these are good
These seem to be the sort of “standard” optocouplers now, the old 4n25-4n33 etc. line doesn’t have nearly as good specs. These are marked “sharp” and seem to match the manufacturer’s codes according to the data sheet, and they are marked with a rank of C, although who knows if they are authentic... so the real test was to actually measure the current transfer ratio. At a LED current of 5 mA, in my batch of 20 of these, the output current at 5v ranged from 11.7-13.7 mA with only one unit measuring lower than 12 mA. This is well within the spec of 10-20 mA for rank C. I didn’t try buying these from any other sellers so I can’t compare or vouch for anyone else but these from Gikfun, but I think it’s fair to say that these are good quality, even if they are not authentic Sharp.
