Safe Operating Guidelines / Absolute Maximum Ratings:
For getting long term performance with IRFP450 do not drive it to its absolute maximum ratings and always stay 20% below from these absolute max ratings. The maximum drain to source voltage is 500V so do not drive load of more than 400V, the maximum continuous drain current is 14A so do not drive load of more than 11A. Use a suitable heatsink with the transistor and always store or operate the MOSFET in temperature -55°C and below +150 °C.
