1. Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site
2. Per SEMI G38-87 and JEDEC JESD51-2 with the single layer board horizontal.
3. Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL
(board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and board
thermal resistance.
