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.
