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

“AH110” 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.

JEDEC Standard J-STD-020

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
