PowerFlat™ Packaging Innovation
Housed in a space-saving PowerFlat™ 5x6 surface-mount package, this MOSFET offers dual benefits of compact design and superior thermal management. The package's low-profile construction (8-PowerVDFN) facilitates automated assembly while maintaining excellent heat dissipation through its exposed pad. This thermal efficiency reduces the need for additional cooling components, enabling designers to create more compact and cost-effective solutions.
The device's ±22V gate voltage tolerance provides enhanced reliability in voltage transient scenarios, while its 1V gate threshold voltage ensures compatibility with standard logic-level drivers. The integrated protection features, combined with 80W power dissipation capability, make it a reliable choice for high-reliability applications.
Comprehensive Performance Metrics
Beyond its headline specifications, the STL140N4LLF5 demonstrates exceptional dynamic performance characteristics. The device's 5900pF input capacitance at 25V Vds contributes to stable operation in high-frequency switching applications. Its 4.5V/10V dual drive voltage capability offers design flexibility, allowing engineers to optimize between gate drive losses and conduction efficiency.
For industrial automation systems, electric vehicles, and energy-efficient computing platforms, this MOSFET provides a critical advantage in power density and system efficiency. The RoHS-compliant PowerFlat package meets modern environmental standards while maintaining mechanical robustness for automated manufacturing processes.
