RJA
= junction to ambient thermal resistance (°C/W)
RJC
= junction to case thermal resistance (°C/W)
RCA
= case to ambient thermal resistance (°C/W)
RJC is device related and cannot be influenced by the user. The user controls the thermal environment to change the case to
ambient thermal resistance, RCA. For instance, the user can change the size of the heat sink, the air flow around the device, the
interface material, the mounting arrangement on printed circuit board, or change the thermal dissipation on the printed circuit
board surrounding the device.
To determine the junction temperature of the device in the application when heat sinks are not used, the Thermal
Characterization Parameter (
JT) can be used to determine the junction temperature with a measurement of the temperature at
the top center of the package case using Equation 3:
TJ = TT + (JT x PD)
Eqn. 3
where:
TT
= thermocouple temperature on top of the package (°C)
JT
= thermal characterization parameter (°C/W)
PD
= power dissipation in the package (W)
The thermal characterization parameter is measured per JESD51-2 specification using a 40 gauge type T thermocouple epoxied
to the top center of the package case. The thermocouple should be positioned so that the thermocouple junction rests on the
package. A small amount of epoxy is placed over the thermocouple junction and over about 1 mm of wire extending from the
junction. The thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects
of the thermocouple wire.
