TYPICAL THERMAL CHARACTERISTICS
Measured at 25 C ambient. These parameters are not tested.
Plastic
The data listed for plastic
flow paths in plastic-encapsulated devices are complex, making the
surface. Tests indicate this measurement reference point is directly below the die-attach area on the bottom center of the package.
