Ok, I picked 1 device out of a whole series which of devices which go up to 100v, 60 amps. They are brand new, but already available. I know about the poor leakage current, but when they are priced at around 1$ at digikey when a comparable schottky with an extra 100mv to 200mv at the same current and speed comes in above 7$ each, these devices have a market, even with some reverse current and capacitance limitations, they have their use and market.
I'm making a 3 phase PMG 30V generator and I would rather pay 5$ using these instead of 40$ in schottky equivalent where I would still loose more wattage due to the larger voltage drop. This is a lot of money after building 1k units. After 2k units, since my original design was priced with schottky in mind, I have enough in pocket for a nice new car...
I'll be going up in voltage and be using this guy 100v, 40amp guy:

OOOOPPPPSSS, just found some 35 amp 100v schottky from Vishay with comparable price. Schottky diodes above 35 amps for some reason sky-rocket in price.
