What are you using them for? There are feedback circuits (and feed-forward circuits) that, in some applications, can reduce the forward drop to essentially zero.BladeSabre said:I'm using BAT754 Schottky diodes, which have a forward voltage drop of 0.2V (at very small currents only). I've not come across anything better than that.

An exotic MOS one. They make a difference in SMPS supplies.

Vishay has a nice selection of diodes.
Protection circuits for chips where the inputs can't go below -0.3V. I'd be very interested to hear about that though.What are you using them for? There are feedback circuits (and feed-forward circuits) that, in some applications, can reduce the forward drop to essentially zero.
"100's of mV" >= 0.2VSo I'm correct in my assumption that for a traditional two-terminal diode that we can only get down to 0.2V forward voltage typically using Germanium, however can get down into the regions of 100's of mV using MOS technology?
Ignore my stupidity! I was thinking that the MOS technology had forward voltages in the region of 100's of micro-volts. As it happens I can't read or type.BladeSabre said:"100's of mV" >= 0.2V
