FH1
High Dynamic Range FET
FH1-G Mechanical Information
This package is lead-free/Green/RoHS-compliant. The plating material on the leads is NiPdAu. It is compatible with both lead-free
(maximum 260
qC
reflow temperature) and leaded (maximum 245
qC
reflow temperature) soldering processes.
Outline Drawing
Product Marking
The FH1-G will be marked with an “FH1G”
designator.
An alphanumeric lot code
(“XXXX-X”) is also marked below the part
designator on the top surface of the package.
The obsolete tin-lead package is marked with
an “FH1” designator followed by an
alphanumeric lot code.
Tape and reel specifications for this part are
located on the website in the “Application
Notes” section.

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

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.
