θjc Considerations
The data listed for plastic
θjc 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
θjc 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,
θjc 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.
