Stresses above 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 in the Electrical Characteristics is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
NOTE1: In a well-ventilated.
NOTE2: When the device is installed in TC>25°C the radiator should be a derating.
