(1) Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to Absolute Maximum rated conditions for extended periods may affect device reliability.

(1) RθJC is determined with the device mounted on a 1-inch² (6.45 -cm²), 2-oz (.071-mm thick) Cu pad on a 1.5-inches × 1.5-inches,
0.06-inch (1.52-mm) thick FR4 board.
(2) RθJB value based on hottest board temperature within 1-mm of the package.
