The values for thermal resistance are achieved by package simulations for the 9S12XEQ512 die.
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.
