This is the datasheet of the Schottky diodes CR6 and CR7: http://www.semicon.panasonic.co.jp/ds4/DB2W319_E.pdf.
I recommend you to check the BOM of the Arduino Expansion Board: Intel® Edison Boards — Arduino* Bill of Materials. That's how I find what the diode model is.
Thanks! The referenced datasheet specifies a max average forward current of 3 A. I can easily stay well below that limit.
Thanks also for providing the link to the BOM, very useful.
