Flyback diode 2 in series

[rakeshm55]

Hi..
I have a fan cntrl design where in I need to place a flyback diode across a 48V brushless type fan 19W .... I want to use smd type diode....i already have Schottky key type diode 40V max reverse voltage in stock....Can I place 2 of such diode in series as flyback (40+40)...Will such design be sturdy ??. Or do I need to choose diode with higher reverse voltage.....I was trying to avoid procurement of new parts .....pls advice
