Safe Operating Guidelines / Absolute Maximum Ratings:

For long term performance do follow these guidelines in your design or circuit. Do not use the transistor on its absolute maximum ratings and always stay 20% below from its max ratings. The maximum drain to source voltage is 200V therefore do not drive load of more than 160V, the maximum continuous drain current is 33A so do not drive load of more than 24A, use suitable heatsink with the transistor and always store or operate the transistor in temperature above -55°C and below +150 °C.
