AH114-89G (Green / Lead-free SOT-89 Package) Mechanical Information

This package is lead-free/Green/RoHS-compliant. It is compatible with both lead-free (maximum 260



C reflow temperature) and leaded

(maximum 245



C reflow temperature) soldering processes. The plating material on the leads is NiPdAu.

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, 150 mA at an 85



C case temperature. A minimum MTTF of 1 million hours is achieved

for junction temperatures below 247



C.

Mounting Config. Notes

1. Ground / thermal vias are critical for the proper performance of this

device. Vias should use a .35mm (#80 / .0135

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.
