the gurus appear to have left the building temporarily  :)

this is the next highest amperage rating i could find in Farnell at a first pass, above Romero's existing level of current draw:

(SB1240: 12A,  40V rev,  0.45V fwd)
http://uk.farnell.com/semikron/sb1240/diode-schottky-12a-40v-axial/dp/1776353

i would have thought that a 6A (30V rev, 0.45V fwd) rating would be sufficient for a system operating at around 50Watt (motor + load), if you can find some in your usual suppliers

hope this helps
np




Also quite nice:

MBR 1645
Schottky 16A 45V TO220 about 0.70 Euros so about 1 US$ per pice.

I have lots of them, a big box full of S30D45CS ; SBL1640CT; STPS3045CW; STPR1620CT,SB3045ST; S20C10CC,....
I have tested those and performance was lower than existing ones 1n4001. Maybe they do work good but at higher frequency BUT not in my current setup.
Maybe someone can explain and help me decide what to use in the next setup.

Hi Romerouk:
   I was able to get amorphous alloys, But also in accordance with the requirements and the size of my production, If I use it to make the coil core, Will get better effect?

   The following are commonly used in magnetic parameters of comparison:
