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. (2) All voltage values are with respect to ANODE, unless otherwise noted.

The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
