In today's global electronics industry, resilience and diversification are critical. Engineers and procurement teams worldwide are actively seeking reliable, high-performance alternatives to established components to strengthen supply chains. If you are evaluating the popular N-channel MOSFET, Infineon's IRFZ24NPBF, consider the advanced Chinese-designed alternative: VBsemi's VBM1680.
This is not just a drop-in replacement. The VBM1680 offers a strategic upgrade, delivering robust electrical performance while providing the stability and cost benefits of a modern, diversified supply source.
Beyond Replacement: Enhanced Technical Performance
While the IRFZ24NPBF is a proven, field-tested component with its 55V, 17A rating, the VBM1680 builds on this foundation for improved efficiency. Designed with a similar 60V drain-source voltage and industry-standard TO-220 package, it delivers key enhancements where it matters:
Optimized Conduction Performance: The VBM1680 features a low on-resistance (RDS(on)) of 72mΩ at 10V gate drive, closely matching the IRFZ24NPBF's 70mΩ while offering improved consistency and modern manufacturing advantages.
Higher Current Capability: The continuous drain current is increased to 20A, providing greater margin over the original 17A. This allows engineers more design flexibility and reliability when handling peak currents or operating in demanding thermal conditions.
Superior Gate Threshold and Voltage Ratings: With a gate threshold voltage of 1.7V and gate-source voltage tolerance of ±20V, the VBM1680 ensures robust switching performance and enhanced compatibility with modern low-voltage drive circuits.
Where It Excels: Application Benefits
The technical strengths of the VBM1680 translate into tangible benefits across key applications:
Power Management Systems: In DC-DC converters, voltage regulators, and power distribution circuits, lower conduction losses and higher current handling improve efficiency and thermal performance, supporting more compact designs.
Motor Drive and Control: For automotive accessories, small industrial motors, and consumer appliances, the combination of low RDS(on) and high current capability reduces heat generation during start-up and high-load conditions, enhancing reliability and longevity.
Switching and Load Switching: The device's fast switching characteristics and robust voltage ratings make it ideal for high-frequency switching applications, including SMPS secondary-side rectification and electronic load control.
The Strategic Value: Performance and Supply Chain Resilience
Choosing the VBM1680 benefits both your technical design and supply chain strategy:
Guaranteed Performance Parity: The datasheet confirms that the VBM1680 meets or exceeds key specifications of the IRFZ24NPBF, ensuring a smooth and low-risk design transition.
Mitigate Supply Chain Risk: Sourcing from a leading Chinese manufacturer like VBsemi diversifies your supply base, reducing dependency on single-source suppliers and protecting against geopolitical uncertainties or market volatility.
Cost Efficiency: Competitive pricing from domestic Chinese components can lower overall system costs, enhancing product competitiveness without compromising quality or reliability.
Conclusion: A Smart Choice for Modern Electronics
VBsemi’s VBM1680 is more than an alternative—it is a forward-looking component choice for the global market. It delivers the proven performance needed to confidently replace the IRFZ24NPBF, offers tangible efficiency improvements, and comes with the strategic advantages of a diversified, resilient supply chain.
For your next-generation power management, motor control, or switching design, evaluating the VBM1680 isn’t just about finding a substitute—it’s about upgrading to a smarter, more sustainable solution.
