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. Directly soldered on 4 layer PCB with thermal vias, thermal resistance from junction to ambient with no airflow is around 40~45 ° C/W (depends
on filled vias or not). Directly soldered on 4 layer PCB without thermal vias, thermal resistance from junction to ambient with no air flow is
around 56 ° C/W.
2. This device is sensitive to electrostatic discharge. Follow proper handing procedures.
