Safe Operating Guidelines / Absolute Maximum Ratings:

In order to use this transistor safely and achieve stable long-term performance with it, it is recommended not to use the transistor at its absolute maximum rating and always keep it 20% below from its max ratings. Using the transistor to its absolute maximum ratings can result in damage to the transistor, shorten its life, or impair its performance.

The maximum drain to source voltage is 30V therefore do not drive load of more than 24V. The maximum forward gate current is 10mA therefore do not drive load of more than 8mA and always store or operate the transistor at temperature above -55°C and below +150 °C.
