Characteristic
Theta-JA determined on 2s2p test boards is frequently lower than would be observed in an application.
Determined on 2s2p thermal test board.
Junction to ambient thermal resistance, Theta-JA (R
JEDEC specification JESD51-2 in a horizontal configuration in natural convection. Theta-JA was
also simulated on a thermal test board with two internal planes (2s2p where “s” is the number of
signal layers and “p” is the number of planes) per JESD51-6 and JESD51-7. The correct name for
Theta-JA for forced convection or with the non-single layer boards is Theta-JMA.
Junction to case thermal resistance, Theta-JC (R
measured values using the cold plate technique with the cold plate temperature used as the “case”
temperature. The 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.
Thermal Characterization Parameter, Psi-JT (
point thermocouple on top center of case as defined in JESD51-2.
estimate junction temperature in steady state customer environments.
