†
Stresses beyond those listed under “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.
‡
These values apply for t

≤ 100 µs, duty cycle ≤ 20%.
NOTE 1: The package thermal impedance is calculated in accordance with JESD 51-7.
