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. Internally limited by thermal shutdown, 150°C min.
2. 2 layer board, 1 in² Cu, 1 oz thickness.
3. 60−180 seconds minimum above 237°C.
NOTE: This device is ESD sensitive. Use standard ESD precautions when handling.
