Notes:
1. Operation of this device above any one of these
parameters may cause permanent damage.
Mounting Instructions
The data shown was taken on a 31mil thick FR-4 board with
1 ounce of copper on both sides.
The board was mounted to a baseplate with 3 screws as shown.
The screws bring the top side copper temperature to the same
value as the baseplate.
1. Use 1 or 2 ounce copper, if possible.
2. Solder the copper pad on the backside of the device
package to the ground plane.
3. Use a large ground pad area with many plated through-holes
as shown.
4. If possible, use at least one screw no more than 0.2 inch
from the device package to provide a low thermal resistance
path to the baseplate of the package.
5. Thermal resistance from ground lead to screws is
2 deg. C/W.
