STF140N6F7

STF140N6F7 is an STMicroelectronics N‑channel power MOSFET from the STF (TrenchFET) family. It is designed as a high‑current switching element for power electronics such as DC‑DC converters, motor drives, and inverters. The device combines low on‑resistance with fast switching, enabling efficient conduction and rapid turn‑on/turn‑off with a gate drive that is often compatible with logic levels. It features the intrinsic body diode and rugged switching/avalanche performance typical of ST’s power MOSFETs. The part name indicates a high‑current, relatively low‑voltage class device (high current ~140 A range, ~60 V class), available in common power packages. For exact specs (Vds, Id, Rds(on), Qgs, Vth, packaging), refer to the official datasheet and supplier tables.

There is no single guaranteed drop‑in equivalent to the STF140N6F7. Match: VDS ≈ 60 V, continuous ID ≥ 140 A, similar RDS(on) and same package/pinout and thermal specs. Common alternative families to search (verify datasheets/pinout): Infineon OptiMOS 60 V parts, Vishay SiHEXFET/SiR 60 V low‑RDS(on) MOSFETs, ON Semiconductor 60 V power MOSFETs, and other ST SuperFET products. Always confirm RDS(on), gate charge, SOA and package compatibility before substituting.

ST STF140N6F7 is an N-channel trench MOSFET. Key features typically include:
- N-channel enhancement mode with trench technology for very low on-resistance
- High current capability for power switching
- Low gate-charge and drive requirements for efficient operation
- Fast switching with low switching losses
- Rugged performance: good avalanche energy rating and robust body diode
- Wide operating temperature range (often suitable for automotive/industrial)
- Package option commonly F7 (D²PAK/DPAK family) suitable for high-current applications
Note: exact Vds, Id, Rds(on), and packaging can vary by subfamily; check the latest datasheet for precise ratings.

STF140N6F7 is an N-channel MOSFET (enhancement mode) used as a power switch. In its D²PAK/TO-263 package it has 3 pins plus a drain tab (4 electrical connections in total). Pinout (top view): Pin 1 = Gate (G), Pin 2 = Drain (D), Pin 3 = Source (S); the metal tab is also Drain.
