Notes:
1.
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
θ
JA
) was simulated to be equivalent to the
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
θ
JC
), was simulated to be equivalent to the 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 (
Ψ
JT
), is the "resistance" from junction to reference
point thermocouple on top center of case as defined in JESD51-2.
Ψ
JT
is a useful value to use to
estimate junction temperature in steady state customer environments.
Junction temperature is a function of on-chip power dissipation, package thermal resistance,
mounting site (board) temperature, ambient temperature, air flow, power dissipation of other
components on the board, and board thermal resistance.
See Section 5.1 from more details on thermal design considerations.
