I recently bought a couple of 'STM' 1N5711 diodes via EBay and measured/compared them to the 'STM' 1N5711 I've bought via Mouser.
The forward voltages differed quite a bit:
Mouser 1N5177 -> 353mV @ 1mA
EBay 1N5177 -> 242mV @ 1mA
Mouser 1N5177 -> 270mV @ 0.1mA
EBay 1N5177' ->192mV @ 0.1mA
Mouser capacitance 1pF
EBay capacitance 12pF
I'm starting to suspect that the Ebay part is a relabeled BAT46?
I've attached a picture with the EBay 'STM 5711' on top.
Any input/thoughts appreciated.
