In an era where supply chain diversification is paramount, engineers globally are seeking reliable, high-performance alternatives to legacy components. For those evaluating the established N-channel MOSFET, Infineon's IRFI1310NPBF, we present the advanced Chinese-designed solution: VBsemi's VBMB1104N.
This is not a simple drop-in replacement. The VBMB1104N is a strategic upgrade, delivering superior electrical performance while providing the stability and cost benefits of a modern, diversified supply source.
Beyond Replacement: A Technical Performance Leap
While the IRFI1310NPBF is a proven component rated at 100V and 24A, the VBMB1104N builds upon this foundation for significantly enhanced performance. Featuring the same 100V drain-source voltage and industry-standard TO-220F package, it delivers critical improvements:
Lower Conduction Losses: The VBMB1104N achieves an exceptionally low on-resistance (RDS(on)) of 34mΩ at a 10V gate drive, outperforming the IRFI1310NPBF's 36mΩ. This reduction directly translates to higher system efficiency and cooler operation.
Substantially Higher Current Capacity: The continuous drain current is dramatically increased to 50A, offering a major advantage over the original 24A rating. This provides engineers with greater design headroom, enhanced robustness for inrush currents, and improved performance in demanding thermal conditions.
Quantifiable Efficiency Gain: Applying the conduction loss formula P = I² x RDS(on), the VBMB1104N's lower resistance yields significantly reduced power dissipation across the load range. This efficiency gain simplifies thermal management, reduces heatsinking requirements, and boosts overall system reliability.
Where It Excels: Application Benefits
The technical superiority of the VBMB1104N delivers tangible benefits in key applications:
Power Supply Units (PSU) & Converters: In switch-mode power supplies (SMPS), DC-DC converters, and power inverters, its lower RDS(on) and high 50A current rating enable more efficient, compact, and higher-power-density designs, aiding compliance with stringent energy standards.
Motor Drive and Control Systems: For applications in power tools, automotive systems, and industrial automation, the reduced conduction losses minimize heat generation during start-up and high-load conditions, leading to higher efficiency, improved reliability, and extended system life.
General Power Switching: Its robust specifications make it an excellent choice for any high-current switching application requiring efficiency and thermal performance.
The Strategic Value: Performance & Supply Chain Resilience
Selecting the VBMB1104N benefits both your technical design and your supply chain strategy.
Guaranteed Performance Superiority: The datasheet confirms it meets or exceeds all key specifications of the IRFI1310NPBF, ensuring a seamless, low-risk design transition with immediate performance gains.
Mitigate Supply Chain Risk: Sourcing from a leading Chinese manufacturer like VBsemi diversifies your supply base, creating a buffer against geopolitical uncertainties, allocation shortages, or price volatility from single-source suppliers.
Cost Efficiency: The competitive pricing of domestic Chinese components can reduce overall system cost, enhancing your product's market competitiveness without compromising on quality or performance.
Conclusion: The Intelligent Choice for Next-Generation Designs
VBsemi’s VBMB1104N is more than an alternative; it is a forward-looking component choice for the global market. It delivers the proven performance to confidently replace the IRFI1310NPBF, adds measurable efficiency improvements, and comes with the strategic advantages of a diversified, resilient supply chain.
For your next-generation power supply, motor drive, or high-current switching design, evaluating the VBMB1104N isn't just about finding a substitute—it's about upgrading to a smarter, more powerful, and more sustainable solution.
