The TO-220FP package is common across many ST power MOSFETs, but pin-compatibility with a current-production sibling is not guaranteed without a cross-reference. When quoting this part, confirm the date-code spread and packaging condition; sealed factory tubes with consistent date-codes are the preferred lot. ## Junction temperature range and deployment context The 175°C TJ(max) makes it a candidate for under-hood automotive, engine-bay electronics, or downhole instrumentation where ambient temperatures push past 125°C. At 175°C junction, the Rds(on) roughly doubles from the 25°C value, so the 10.5 mOhm headline number is a best-case figure; budget 20 mOhm or more at high temperature for loss calculations. ## Gate drive and switching considerations This is a standard-threshold device — a 5 V logic gate will not fully enhance it; use a proper gate driver that swings to 10 V or more. Input capacitance (Ciss) is 5200 pF at 25 V Vds, which influences the driver's peak current requirement for fast turn-on edges.","metaTitle":"STF120NF10 STripFET II N-Channel MOSFET, 100 V, 41 A","metaDescription":"STF120NF10 N-channel MOSFET, 100 V, 41 A, 10.5 mOhm Rds(on).
