Package Thermal Characteristics
The VSC7121 is packaged into a standard plastic quad flatpack with an embedded, but unexposed thermal
slug. This package adheres to industry standard EIAJ footprints for a 10x10mm body, 44 lead PQFP. The pack-
age construction is as shown in Figure 6. The 44 PQFP with embedded slug has the thermal properties shown in
Table 5. This package allows the VSC7121 to operate with ambient temperatures up to 70
o
C in still air.
