Oh hell, I get your point now Ross. Regarding the 100% duty cycle.
Yes, just pointing out that a great many diodes are rated for their half-wave, sinusoidal current - a totally different animal.
What about these instead of a schottky?
Well, first off - the bulk of the reason I used schottky in the first place was the lower V(f). Double the V(f) and you double the power the device has to dissipate. So the diode with the lowest forward drop that'll do the job, is the best option for the job IMHO.
Second - the device you quoted, claims 16A - however the tech specs say:
"Average Rectified Forward Current Per Diode, (Rated VR), TC = 150C" ..... 8A
In your case, the DC current IS the "Average Rectified Forward Current"
You could use either device - but if you want some safety margin, I think I'd be using both halves of a pack PER ARRAY, whichever device you settle on.
