CONCLUSIONS
As a derivative of the PowerPAK SO-8, the PowerPAK
1212-8 uses the same packaging technology and has
been shown to have the same level of thermal perfor-
mance while having a footprint that is more than 40 %
smaller than the standard TSSOP-8.
Recommended PowerPAK 1212-8 land patterns are
provided to aid in PC board layout for designs using this
new package.

The PowerPAK 1212-8 combines small size with attrac-
tive thermal characteristics. By minimizing the thermal
rise above the board temperature, PowerPAK simplifies
thermal design considerations, allows the device to run
cooler, keeps r
handle more current than a same- or larger-size MOS-
FET die in the standard TSSOP-8 or SO-8 packages.
