56F827 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.
