Ban, Try opening up almost any PC power supply and lookup the parts numbers on the rectifier diodes, all of them. They're sometimes plain diodes, but often on the secondary side they're Schottky. Lesee here, picking two diodes I've salvaged, at random:
BYS28-45 - Schottky 20 amp dual diode
D83-004 Schottky 40 amp dual diode.
.... hmmm... about 600,000,000 PC power supplies made.... I've opened up about a dozen of them, and never seen a faulty diode. Lots of frozen fans, popped capacitors, blown fuses, never a blown schottky diode.
So hundreds of PC power supply designers are wrong, 600 million PC power supplies are defying your laws of physics, and you're right about schottky.s hmmmmm......
