Notes:

1. The thermal resistance is referenced from the junction-to-

case at a case temperature of 85 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

2. This corresponds to the typical biasing condition of +5V,

250 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

“AH115-S8” 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

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.
