Preliminary Data Sheet
Table 8. Package Thermal Specifications
Thermal resistance values for the PPC440SPe package in a convection environment are as follows:
Airflow ft/min (m/sec)
Parameter
Symbol
0 (0)
Junction-to-case thermal resistance
Case-to-ambient thermal resistance (w/o heat sink)
100 (0.51)

13.1
Range
Minimum
Junction-to-ball (typical)
Notes:
1. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board. For this part the junction
temperature and the case temperature are essentially identical.
2. The case-to-ambient thermal resistance is measured in a JEDEC JESD51-6 standard environment; and may not accurately
predict thermal performance in production equipment environments. The operational case temperature must be maintained.
3. 6.5 °C/W is the theoretical
θ
JB using an infinite heat sink. The larger number applies to the module mounted on a 1.8mm thick,
2P card using 1oz. copper power planes, with an effective heat transfer area of 75mm
