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 maximum package power dissipation limit must not be exceeded.
2. The value of qJA is measured with the device mounted on 2in x 2in FR−4 board with 2oz. copper, in a still air environment with T
3. 60−180 seconds minimum above 237°C.
