    Note:
    1. Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site
    (board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and board
    thermal resistance.
    2. Per JEDEC JESD51-2 with the single layer board horizontal. Board meets JESD51-9 specification.
    3. Per JEDEC JESD51-6 with the board horizontal.
    4. Thermal resistance between the die and the printed circuit board per JEDEC JESD51-8. Board temperature is measured
    on the top surface of the board near the package.
    5. Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883
    Method 1012.1).
    6. Thermal characterization parameter indicating the temperature difference between package top and the junction
    temperature per JEDEC JESD51-2. When Greek letters are not available, the thermal characterization parameter is
    written as Psi-JT.
