high voltage - Would the FCA47N60F work for a ZVS flyback driver?

I have built a few flyback drivers from 555 controlled to the ZVS. I always have one problem, the power transistors keep burning out. For the ZVS driver, I used the IRFP250 and keep having the problem of transistor failure over about 24 volts for the input. Here's a schematic of the ZVS.

I recently ordered some FCA47N60F 600 volt 47 amp MOSFETs on sale at electronic goldmine. Would these transistors work with the circuit, or are there specific transistor properties needed for the circuit?
