Advance Product Information
VSC7133
G52187-0 Rev. 2.4
Thermal Considerations
The VSC7133 is packaged in a 10mm, thermally enhanced PQFP with an internal heat spreader. These
packages use industry-standard EIAJ footprints, but have been enhanced to improve thermal dissipation. The
construction of the packages are shown below.
Figure 10: Package Cross Section
Table 6: Thermal Resistance
The VSC7133 is designed to operate with a case temperature up to 95
o
C. The user must guarantee that the
case temperature specification is not violated. With the thermal resistances shown above, the 10mm Thermally
Enhanced PQFP can operate in still air ambient temperatures of 50
o
C [50
o
C = 95
o
C - 0.9W * 50]. If the ambient
air temperature exceeds these limits then some form of cooling through a heatsink or an increase in airflow must
be provided.
Moisture Sensitivity Level
This device is rated at with a Moisture Sensitivity Level 3 rating. Refer to Application Note AN-20 for
appropriate handling procedures.
