Any fast recovery diode that can handle the voltage/current/power will work. The important thing to look for is 'fast recovery' when chosing a flyback diode. All diodes have a switching time as the voltage reverses, in a situation involving the voltage created from an inductor suddenly starved of power the voltage/current spike occurs VERY quickly, rectifier diodes would let most of the spike occur, fast recovery diodes are constructed to minimize that as much as possible.
