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 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. See
Tech Brief TB379.
3. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
4. Limits should be considered typical and are not production tested.
E^Z lectrical Specifications
Recommended Operating Conditions. Parameters with MIN and/or MAX limits are 100% tested at +25°C,
unless otherwise specified. Temperature limits established by characterization and are not production
tested.
