Mounted and soldered directly to the surface of the pc board and requiring no secondary attachment mechanisms, this new line of surface-mount heatsinks has been developed for cooling D2-Pak and SO-10 packages. Designed to reduce heatsink installation costs while maintaining the sink's thermal integrity, the line includes Models 7106D and 7109 offering thermal resistance specs of 16.25°C/W and 11.25°C/W, respectively. Both sinks are made of a copper alloy having a Sn/Pb solder plating.
