TYPICAL THERMAL CHARACTERISTICS
Measured at 25

C ambient. These parameters are not tested.

Considerations
The data listed for plastic
θ
jc
are for reference only and are not recommended for use in calculating junction temperatures. The heat-
flow paths in plastic-encapsulated devices are complex, making the
θ
jc
measurement relative to a specific location ion the package
surface. Tests indicate this measurement reference point is directly below the die-attach area on the bottom center of the package.
Furthermore,
θ
jc
tests on packages are performed in a constant temperature. Therefore, the measurements can only be used in a
similar environment.
