Package Thermal Characteristics
The device junction to case thermal characteristic is
θ
jc
,
and the junction to ambient air characteristic is
θ
ja
. The
thermal characteristics for
θ
ja
are shown with two different
air flow rates.
Maximum junction temperature is 150
°
C.
A sample calculation of the absolute maximum power
dissipation allowed for an RT54SX16 in a CQFP 256-pin
package at military temperature and still air is as follows:
