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.
NOTES:
5. θ is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
JA
6. For θ , the “case temp” location is the center of the exposed metal pad on the package underside.
JC
7. For θ , the “case temp” location is taken at the package top center.
