56F826 Technical Data
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.
