Notes:

1. The thermal resistance is referenced from the

junction-to-case at a case temperature of 85

° C.

2. This corresponds to the typical biasing condition of

+5V, 100 mA at an 85

° C case temperature. A

minimum MTTF of 1 million hours is achieved for

junction temperatures below 247

° C.

Product Marking

The component will be marked with an “E015G”

designator with an alphanumeric lot code on the

top surface of the package.

Tape and reel specifications for this part are

located on the website in the “Application Notes”

section.

Mounting Config. Notes

1. 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”).

2. Add as much copper as possible to inner and outer layers

near the part to ensure optimal thermal performance.

3. 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.

4. Do not put solder mask on the backside of the PC board in

the region where the board contacts the heatsink.

5. RF trace width depends upon the PC board material and

construction.

6. Use 1 oz. Copper minimum.

7. All dimensions are in millimeters (inches). Angles are in

degrees.
