Since the 1N5818 on the motorfaderboard are not avaiable in SMD package I want to replace them. What properties must the diodes have? And what must not?
Can I take any shottky diode with a 1A current?
Or is 1A too much?

You can’t go lower than the specified rating of Thorsten’s circuit, which probably rules out SMD, I don’t know of equivalent to 1N5818
That implies Thorsten’s design is on the lower limit…
I just took the cheapest shottky diodes which are available at Reichelt. 
I guess that shottkys with I_tot=0.25A should also work
Best Regards, Thorsten.
Ok, so it is well above the minimum current handling!
