The 142 nC gate charge at 10 V requires a driver capable of sourcing a solid current pulse. Rated for 80 A continuous drain at 25 °C case temperature, derate at higher ambient. The D2PAK (TO-263) footprint fits standard surface-mount assembly. Junction temperature spans -55 to 175 °C, which covers under-hood automotive, industrial motor drives with hot enclosures, and outdoor telecom cabinets. The wide range also means the part can handle brief overload events without immediate failure — useful for inrush or short-circuit withstand in a breaker-less design. No AEC-Q101 qualification is listed in the record, so verify with ST if automotive-grade certification is required for your program. STB140NF55T4 carries an Active product status, so it remains in normal production with no last-time-buy risk. ROHS3 compliant — no exemptions expiring.","metaTitle":"STB140NF55T4 N-Channel MOSFET, 55V 80A D2PAK, STripFET II","metaDescription":"STB140NF55T4 N-channel 55V 80A MOSFET in D2PAK. 8 mOhm Rds(on) at 10V.
