Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

This is the inverse of the traditional Junction-to-Ambient thermal Resistance (RΘJA). Thermal Resistances are not production tested and the
values given are for informational purposes only. Values are based on modeled data for the 48-PFB on a FR-4 board structure per JESD-51-7,
High Effective Thermal Conductivity Test Board for Leaded Surface Mount Packages.
