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. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.
3. Limits should be considered typical and are not production tested.
Electrical Specifications
Recommended Operating Conditions, Unless Otherwise Noted. 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.
