The values for thermal resistance are achieved by package simulations for the 9S12XEP100 die.
Measured per JEDEC JESD51-8. Measured on top surface of the board near the package.
Junction to ambient thermal resistance, θ
horizontal configuration in natural convection.
Junction to ambient thermal resistance, θ
horizontal configuration in natural convection.
Junction to case thermal resistance was simulated to be equivalent to the measured values using the cold plate technique with
the cold plate temperature used as the “case” temperature. This basic cold plate measurement technique is described by
MIL-STD 883D, Method 1012.1. This is the correct thermal metric to use to calculate thermal performance when the package
is being used with a heat sink.
