STI270N4F3 Description

The STI270N4F3 from STMicroelectronics is a high-performance N-channel 40V, 160A (Tc) power MOSFET, part of the STripFET™ III series. Designed for automotive-grade applications, it features an ultra-low Rds(on) of 2.6mΩ @ 80A, 10V, ensuring minimal conduction losses and high efficiency in power-switching circuits. Packaged in a robust I2PAK through-hole format, it offers superior thermal dissipation with a maximum power rating of 330W (Tc). Though marked obsolete, its specifications remain competitive for legacy designs requiring high-current handling and reliability.

STI270N4F3 Features

• Low On-Resistance: 2.6mΩ @ 10V Vgs minimizes power loss in high-current paths.
• High Current Capacity: 160A continuous drain current (Tc) supports demanding loads.
• Fast Switching: Gate charge (Qg) of 150nC @ 10V and input capacitance (Ciss) of 7400pF @ 25V balance speed and drive requirements.
• Rugged Design: ±20V Vgs tolerance and automotive-grade qualification ensure durability in harsh environments.
• Thermal Efficiency: I2PAK package optimizes heat dissipation for sustained high-power operation.
• Compliance: ROHS3, REACH unaffected, and MSL 1 (unlimited) for environmental and handling reliability.

STI270N4F3 Applications

• Automotive Systems: Ideal for electric power steering (EPS), DC-DC converters, and 12V/48V battery management due to high current and thermal resilience.
• Industrial Power Supplies: Suited for synchronous rectification and motor drives where low Rds(on) reduces energy loss.
• Legacy Designs: A reliable choice for high-current switching in obsolete-compatible systems requiring proven performance.

Conclusion of STI270N4F3

The STI270N4F3 excels in high-efficiency, high-current applications, leveraging STripFET™ III technology for low conduction losses and robust thermal management. While obsolete, its automotive-grade reliability and I2PAK packaging make it a strong candidate for legacy or niche designs demanding 40V/160A capabilities. Engineers should evaluate alternatives for new designs but can rely on this MOSFET for proven performance in existing systems.
