Vrrm value of the output diode

Hi all;
I have designed an 12V 1A flyback design using TNY278
I want to ask that what happen if the Vrrm value of the output diode is selected small?For example I am using 2A diode with Vrrm=40V
Thanks
Exceeding reverse voltage rating of output diode will cause severe damage to output diode and TNY -- you need to see worst case reverse voltage which at highest input voltage to get an idea of how low you can go with reverse voltage of diode
