JMA and jt parameters are simulated in conformance with EIA/JESD Standard 51-2 for natural convection. Freescale
recommends the use of
JMA and power dissipation specifications in the system design to prevent device junction
temperatures from exceeding the rated specification. System designers should be aware that device junction temperatures
can be significantly influenced by board layout and surrounding devices. Conformance to the device junction temperature
specification can be verified by physical measurement in the customer’s system using the
jt parameter, the device power
dissipation, and the method described in EIA/JESD Standard 51-2.
