â¡ Stresses beyond those listed under âabsolute maximum ratingsâ 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 ârecommended operating conditionsâ is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: Voltage values are with respect to the ANODE terminal, unless otherwise noted.

NOTE 3: Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) â TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
