NOTES:
1. θ JA is measured with the component mounted on a high effective thermal conductivity test board in free air.
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.
