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:
4. _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.
5. _JC, “case temperature” location is at the center of the package underside exposed pad.
Electrical Specifications These specifications apply for recommended ambient temperature, unless otherwise noted. Boldface limits
apply over the operating temperature range.
