Mounting Config. Notes
Land Pattern
1. A heatsink underneath the area of the PCB for the mounted device
is strictly required for proper thermal operation. Damage to the
device can occur without the use of one.
2. Ground / thermal vias are critical for the proper performance of this
device. Vias should use a .35mm (#80 / .0135”) diameter drill and
have a final plated thru diameter of .25 mm (.010”).
3. Add as much copper as possible to inner and outer layers near the
part to ensure optimal thermal performance.
4. Mounting screws can be added near the part to fasten the board to a
heatsink. Ensure that the ground / thermal via region contacts the
heatsink.
5. Do not put solder mask on the backside of the PC board in the
region where the board contacts the heatsink.
6. RF trace width depends upon the PC board material and
construction.
7. Use 1 oz. Copper minimum.
8. All dimensions are in millimeters (inches). Angles are in degrees.

Notes:
1. The thermal resistance is referenced from the hottest part
of the junction to the ground slug underneath the device.
2. This corresponds to the typical biasing condition of
+5V, 800 mA at an 85° C case temperature. A
minimum MTTF of 1 million hours is achieved for
junction temperatures below 247° C. Tjc is a function
of the voltage at pins 6 and 7 and the current applied
to pins 6, 7, and 8 and can be calculated by:
Tjc = Tcase + Rth * Vcc * Icc
