Freescale recommends the use of θ
junction temperatures from exceeding the rated specification. System designers should be aware that device
junction temperatures can be significantly influenced by board layout and surrounding devices. Conformance to the
device junction temperature specification can be verified by physical measurement in the customer’s system using
the Ψ
Per JEDEC JESD51-6 with the board horizontal.
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.
Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883
Method 1012.1).
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.
