STL140N4LLF5 - STMicroelectronics
The STL140N4LLF5 is a high-performance, N-channel Trench MOSFET produced by STMicroelectronics, a leader in semiconductor solutions. This power MOSFET is designed to meet the rigorous demands of a wide range of electronic applications, offering an optimal balance between on-resistance and switching performance, which is crucial for efficient power management in modern electronic devices.
With a maximum continuous drain current of 80A and a drain-source voltage of 40V, the STL140N4LLF5 is capable of handling high current loads while maintaining a low thermal footprint. This is thanks to its advanced STripFET F7 technology, which minimizes on-state resistance (R<sub>DS(on)) to just 1.4 mΩ (max), ensuring high efficiency and reduced power losses during operation.
The device is housed in a robust PowerFLAT™ 5x6 dual-side cooling package, which not only provides excellent thermal performance but also allows for a compact design. This makes the STL140N4LLF5 suitable for space-constrained applications while still delivering the power handling capabilities needed for high-performance systems.
Key features of the STL140N4LLF5 include:
- 100% avalanche tested, providing reliability and robustness in harsh environments.
- Low gate charge (Q<sub>g) and reduced gate resistance (R<sub>g) for faster switching and lower switching losses.
- Low threshold voltage (V<sub>GS(th)) to ensure a better control in the gate drive circuit.
- High avalanche ruggedness, making it suitable for applications that may experience unexpected voltage transients.
Applications for the STL140N4LLF5 are diverse, ranging from high-efficiency switch mode power supplies (SMPS), DC-DC converters, motor control systems, automotive applications, and any power management tasks where efficiency is a priority. Its performance and reliability make it an excellent choice for designers looking to improve the energy efficiency and thermal management of their systems.
STMicroelectronics' commitment to environmental sustainability is evident in the STL140N4LLF5, which is compliant with RoHS and Halogen-free directives. This ensures that it meets the latest environmental standards, making it suitable for use in eco-friendly products.
Whether you're designing power supplies, motor controllers, or any other application requiring efficient power handling and switching, the STL140N4LLF5 from STMicroelectronics offers the performance and reliability needed to meet the challenges of modern electronic designs.
