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:
1. θ JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features.
2. θ JC , "case temperature" location is at the center of the package underside exposed pad. See Tech Brief TB379 for details.
3. Limits should be considered typical and are not production tested.
