Junction temperature is a function of 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.
Per SEMI G38-87 and EIA/JESD51-2 with the single layer board horizontal.
Per JEDEC JESD51-6 with the board (JESD51-9) horizontal.
Thermal resistance between the die and the printed circuit board per JEDEC JESD 51-8. Board temperature is measured on
the top surface of the board near the package.
Thermal resistance between the die and the case top surface without thermal grease. TBD = to be determined. If a thin (less
than 50 micron) thermal grease interface is established to a heat sink from the lid, the junction to sink thermal resistance is
about 0.7 °C/W.
