Notes:
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 (JESD51-3) horizontal.
3.
Per JEDEC JESD51-6 with the board (JESD51-7) horizontal.
4.
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.
5.
Thermal resistance between the active surface of the die and the case top surface determined by the cold plate method (MIL
SPEC-883 Method 1012.1) with the calculated case temperature.
