CAUTION: Stress above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device
at these or any other conditions above those indicated in the operational section of this specification is not implied.
NOTE:
1. θ_JA is measured with the component mounted on a highly effective thermal conductivity test board on free air. See Tech Brief TB379 for details
2. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
