The selection criteria will depend on, how fast your fuse will blow.
firstly, you need to identify what is your short circuit current sourcing capacity of your Input DC Source.
then how fast (means within what time) your selected fuse will get blown.
based on that arcing current you can choose the diode which is conducting throughout that arcing time of the fuse.
selection of that diode is in such a way that, the diode surge current should be at least 2.5 times the arcing current of the fuse within that time.
