Product Information
EC1089B-G (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 qC reflow temperature) and leaded
(maximum 245 qC reflow temperature) soldering processes. The plating material on the leads is NiPdAu.
Outline Drawing
Product Marking
The component will be marked with an
“1089G” designator with an alphanumeric lot
code on the top surface of the package. The
obsolete tin-lead package is marked with a
“1089” designator followed by an
alphanumeric lot code.
Tape and reel specifications for this part are

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.

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,
160 mA at an 85 C case temperature. A minimum
MTTF of 1 million hours is achieved for junction
temperatures below 247 C.
