STF100N6F7 N-channel MOSFET, 60 V Vdss, 46 A continuous drain, 5.6 mOhm Rds(on) max at 23 A, 10 V gate drive.
175 °C junction — thermal headroom for harsh environments
The TO-220FP full-pack package isolates the tab electrically, so no mica washer or thermal grease is needed against the heatsink — the back of the package is the mounting face, and the 25 W power dissipation rating assumes a properly sized heatsink at 25 °C case temperature.
