(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.

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.
