Thermal Characteristics
Thermal characteristics are targets based on simulation that are subject to change per device
characterization.
Junction-to-Ambient Thermal Resistance determined per JEDEC JESD51-3 and JESD51-6. Thermal test
board meets JEDEC specification for this package.
JEDEC specification for the specified package.
Junction-to-Case at the top of the package determined using MIL-STD 883 Method 1012.1. The cold plate
temperature is used for the case temperature. Reported value includes the thermal resistance of the
interface layer.
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.
Thermal characteristics are targets based on simulation that are subject to change per device
characterization.
Junction-to-Board thermal resistance determined per JEDEC JESD51-8. Thermal test board meets
