1. The thermal resistance is referenced from the hottest
part of the junction to the ground tab (pin 4).
2. This corresponds to the typical biasing condition of
+5V, 150 mA at an 85
C case temperature.
A
minimum MTTF of 1 million hours is achieved for
junction temperatures below 160
C.
Product Marking
The AH31 will be marked with an “AH31”
designator.
An alphanumeric lot code
(“XXXX-X” ) is also marked below the part
designator 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.
