Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
1. The Power Dissipation of the package may result in a lower continuous drain
current.
2. Pulse Test: Pulse Width v 300 ms, Duty Cycle v 2.0%.
