The STN3NF06L: The gate threshold is specified at 2.8 V max with 250 µA drain current. On-resistance is guaranteed at 5 V and 10 V drive.
Temperature range and environment — where it goes
The SOT-223 package is a surface-mount part with a large tab for heat sinking — the 3.3 W dissipation limit assumes the tab is soldered to a copper area on the PCB.
