   Schotkeys do have lower barrier potentials than normal diodes. A typical   
   silicon diode has a barrier potential of between 0.6 and 0.7 volts;   
   schotkeys less than half that so it seems slightly low but probably still   
   good. You can always look up the datasheet for that particular diode and   
   see what the Vf should be just to be on the safe side.
