CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTE:
1. θ JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2. θ JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. θ JC, the
“case temp” is measured at the center of the exposed metal pad on the package underside. See Tech Brief TB379.
3. Limits established by characterization and are not production tested.
