I found another possible substitution for the MOSFET ...

International Rectifier IRFPG50

ST Microelectronics STW9N150

N-channel 1500 V - 1.8 Ω - 8 A - TO-247
very high voltage PowerMESH™ Power MOSFET
Single pulse avalanche energy - 720

@ Aaron and Rosemary ....... look at Figure 4 Typical Output Characteristics and Figure 5 Typical Transfer Characteristics everything else appears fairly close.

Best Regards,

Thanks Glen!

Here are your four finds:
Fairchild Semiconductor - FQH8N100C
Fairchild Semiconductor - FQAF11N90C
International Rectifier IRFPG50

ST Microelectronics STW9N150
