THERMAL CHARACTERISTICS
Table 38. Thermal Characteristics for BC-160 Package
To determine the junction temperature on the application
printed circuit board, use:
T J = T CASE + ? ? JT ? P D ?
where:
T J = Junction temperature ( ° C).
T CASE = Case temperature ( ° C) measured by customer at top
center of package.
? JT = From Table 38 through Table 40 .
P D = Power dissipation (see the power dissipation discussion

tion-to-board measurement complies with JESD51–8. The
junction-to-case measurement complies with MIL-STD-883
Table 40. Thermal Characteristics for B-169 Package
(Method 1012.1). All measurements use a 2S2P JEDEC test
board.
Thermal resistance ? JA in Table 38 through Table 40 is the figure
of merit relating to performance of the package and board in a
convective environment. ? JMA represents the thermal resistance
under two conditions of airflow. ? JT represents the correlation
between T J and T CASE .
