Preliminary Data Sheet

Table 8. Package Thermal Specifications

Thermal resistance values for the PPC440SPe package in a convection environment are as follows:

0 (0)

100 (0.51)

200 (1.02)

Junction-to-case thermal resistance

0.8

°C/W

Case-to-ambient thermal resistance (w/o heat sink)

15.5

13.1

11.9

Range

Minimum

Maximum

Junction-to-ball (typical)

6.5

°C/W

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

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 75mm2.

Table 9. Recommended DC Operating Conditions (Sheet 1 of 3)

Device operation beyond the conditions specified is not recommended. Extended operation beyond the recommended

conditions can affect device reliability.
