概述

Description

STF140N6F7 is STMicroelectronics’ N-channel power MOSFET from the STF (SuperTrench/TrenchFET) family. It targets high-current, low-loss switching in 60 V power stages.
Key points:
- Type: N-channel enhancement MOSFET
- Voltage/current: about 60 V drain–source, up to ~140 A continuous (at case temp 25°C)
- Conduction: low on-state resistance (milliohms range) for high efficiency
- Switching: optimized for fast switching and good switching losses
- ruggedness: avalanche-energy capability and robust thermal performance
- packaging: available in common power packages (e.g., D²PAK/TO-263, TO-220 variants)
- gate drive: standard MOSFET gate (Vgs max typically ±20 V; full conduction around 10 V; not guaranteed as a logic-level device)
Applications: DC-DC converters, motor drivers, automotive power electronics, and other high-current switching power stages.
Note: exact electrical specs, thermal limits, and safe operating area are in the STF140N6F7 datasheet—consult it for your design.

Features

STF140N6F7 is a 60 V N-channel trench MOSFET from STMicroelectronics. Key features:
- N-channel enhancement mode MOSFET
- Vds = 60 V; high-current capability (around the 140 A class)
- Low on-resistance for high-efficiency conduction
- Fast switching performance with low gate charge
- Robust avalanche energy capability and rugged body diode for inductive-load protection
- Suitable for synchronous buck/boost converters, DC-DC power supplies, motor drivers, and similar power electronics
- Designed for reliable operation in industrial/consumer power applications
- Pb-free, RoHS-compliant; available in standard power packages
Note: exact values (Rds(on), packaging, and Safe Operating Area) vary by lot and package. For precise numbers, consult the official datasheet.

Package

The STF140N6F7 is supplied in a TO-263 (D2PAK) 3-lead surface-mount power package. Please verify the exact mechanical and thermal specs in the manufacturer’s datasheet.

Pinout

Pin count: 3 external pins (Gate, Drain, Source) plus a metal tab/heat-sink (electrically connected to the Drain).
Function: N‑channel enhancement‑mode power MOSFET used for high‑current switching and load switching (fast, low RDS(on) transistor).

Manufacturer

The STF140N6F7 is manufactured by STMicroelectronics. STMicroelectronics is a multinational semiconductor company (an integrated device manufacturer) that designs and manufactures a broad range of semiconductor products — microcontrollers, analog and power ICs, sensors, and discrete devices such as MOSFETs — with headquarters in Geneva and major operations in Europe and worldwide.

Application

STF140N6F7 is a high‑current N‑channel MOSFET (approx. 60 V, 140 A class). Primary applications:
- Synchronous buck/boost DC‑DC converters and other SMPS switches
- Motor drives and high‑speed switching in automotive/industrial gear
- Solar inverters, power management and energy‑storage electronics
- Load switching, inrush control and general power‑switching tasks
