is the thermal resistance between die junction and
ambient air.
R
θ
JSmn
is the thermal resistance between die junction and
the reference location on the board surface near a center
lead of the package.
This device is a dual die package. Index
m
indicates the
die that is heated. Index
n
refers to the number of the die
where the junction temperature is sensed.
