TYPICAL THERMAL CHARACTERISTICS
Measured at 25 C ambient. These parameters are not tested.
Plastic jc Considerations
The data listed for plastic 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 jc measurement relative to a specific location on the
package surface. Tests indicate this measurement reference point is directly below the die-attach area on the bottom center of the
package. Furthermore, jc tests on packages are performed in a constant-temperature bath, keeping the package surface at a
constant temperature. Therefore, the measurements can only be used in a similar environment.
