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 (with direct attach for DFN) test board in free air. See Tech
Brief TB379 for details.
2. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
