1N5711 knockoff ?

[AHedg.1]

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.

Fake parts from sketchy vendors on eBay..

Certainly in the realm of possibilities.
