dissipation on the printed circuit board surrounding the device. This description is most useful for
packages with heat sinks where 90% of the heat flow is through the case to heat sink to ambient.
For most packages, a better model is required.
A more accurate two-resistor thermal model can be constructed from the junction-to-board thermal
resistance and the junction-to-case thermal resistance. The junction-to-case thermal resistance describes
when using a heat sink or where a substantial amount of heat is dissipated from the top of the package. The
junction-to-board thermal resistance describes the thermal performance when most of the heat is
conducted to the printed circuit board. This model can be used to generate simple estimations and for
computational fluid dynamics (CFD) thermal models.
To determine the junction temperature of the device in the application on a prototype board, use the
thermal characterization parameter (
Ψ
JT) to determine the junction temperature by measuring the
temperature at the top center of the package case using the following equation:
TJ = TT + (ΨJT × PD)
where:
TT = thermocouple temperature on top of the package (
oC)
Ψ
JT = thermal characterization parameter (
oC/W)
PD = power dissipation in the package (W)
The thermal characterization parameter is measured in compliance with the JESD51-2 specification using
a 40-gauge type T thermocouple epoxied to the top center of the package case. Position the thermocouple
so that the thermocouple junction rests on the package. Place a small amount of epoxy on the thermocouple
junction and approximately 1 mm of wire extending from the junction. Place the thermocouple wire flat
against the package case to avoid measurement errors caused by the cooling effects of the thermocouple
wire.
