Product Information
FP31QF-F Mechanical Information
This package is lead-free/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 pins is annealed matte tin over copper.
Product Marking
Outline Drawing
The component will be lasermarked with a
“FP31FF” product label with an alphanumeric
lot code on the top surface of the package.
The obsolete tin-lead package is marked with
an “FP31QF” designator followed by an
alphanumeric lot code.
Tape and reel specifications for this part will
be 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 copper on the backside.
2. This corresponds to the typical drain biasing
condition of +9V, 450 mA at an 85°C case
temperature. A minimum MTTF of 1 million hours is
achieved for junction temperatures below 160 °C.
