Product Information

AG402-89G (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.

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

+4.91V, 60 mA at an 85

°C case temperature. A

minimum MTTF of 1 million hours is achieved for

junction temperatures below 177

°C.

Product Marking

The AG402-89G will be marked with an

“A402G” 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.
