Mounting and Thermal Considerations.”) In this figure, the drain land pattern is given to make full contact to the drain pad on the PowerPAK package. This land pattern can be extended to the left, right, and top of the drawn pattern. This extension will serve to increase the heat dissipation by decreasing the ther- mal resistance from the foot of the PowerPAK to the PC board and therefore to the ambient. Note that increasing the drain land area beyond a certain point will yield little decrease in foot-to-board and foot-to- ambient thermal resistance. Under specific conditions of board configuration, copper weight, and layer stack, experiments have found that adding copper beyond an area of about 0.3 to 0.5 in2 of will yield little improve- ment in thermal performance.

This is a 4.8 °C rise above the board temperature for the Power- PAK 1212-8, and over 40 °C for other SMT packages. A 4.8 °C rise has minimal effect on r whereas a rise DS(ON) of over 40 °C will cause an increase in r as high DS(ON) as 20 %. Document Number 71681 www.vishay.com 03-Mar-06 3
