7 Mechanical Packaging and Orderable Information
This section describes the C6745/6747 orderable part numbers, packaging options, materials, thermal and
mechanical parameters.
This section contains mechanical drawings for the ZKB Plastic Ball Grid Array package and the PTP
PowerPAD™ plastic quad flat pack package. Additionally, for the PTP package a detailed drawing of the
actual thermal pad dimensions as well as a recommended PCB footprint are provided.
7.1 Thermal Data for ZKB
The following table(s) show the thermal resistance characteristics for the PBGA–ZKB mechanical
package.
