Package Thermal Specifications

The PPC405GP is designed to operate within a case temperature range of -40°C to +85°C. Thermal resistance values for the

E-PBGA packages (leaded and lead-free) in a convection environment are as follows:

Notes:

1. For a chip mounted on a JEDEC 2S2P card without a heat sink.

2. For a chip mounted on a card with at least one signal and two power planes, the following relationships exist:

a. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board.

b. TA = TC – P×θCA, where TA is ambient temperature and P is power consumption.

c. TCMax = TJMax – P×θJC, where TJMax is maximum junction temperature and P is power consumption.
