Thermal Considerations
The data shown was taken on a 31 mil thick FR-4 board with 1 ounce copper on both sides. The board was mounted to a base-
plate with 3 screws as shown. The screws bring the top side copper temperature to the same value as the baseplate. The thermal
resistance to the indicated reference lead,
Θ
JL, is 10°C/W. The thermal resistance to the reference screw is 12°C/W.
1. Use 1 or 2 ounce copper if possible.
2. Solder all eight leads of the CFK2162-P5 package to the appropriate electrical connection.
3. Solder the copper pad on the backside of the CFK2162-P5 package to the ground plane.
4. Use a large ground pad area with many plated through-holes as shown.
5. If possible, use at least one screw no more than 0.2 inches from the CFK2162-P5 package to provide a low thermal resistance
path to the baseplate of the package.
