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
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
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.
