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 heat generated must be less than the thermal conductivity from Junction−to−Ambient: dPD/dTJ < 1/RqJA.
