In an era where supply chain diversification is critical, engineers and procurement specialists are actively seeking reliable, high-performance alternatives to mainstream components. If you are considering the robust N-channel MOSFET, Infineon's IRFB7534PBF, for your high-current designs, evaluate the superior Chinese-designed alternative: VBsemi's VBM1602.
This is not just a simple replacement. The VBM1602 represents a strategic enhancement, delivering improved electrical performance while providing the stability and cost benefits of a modern, diversified supply source.
Beyond Direct Replacement: A Technical Advancement
While the IRFB7534PBF is a proven solution with its 60V, 232A rating and features like improved gate and avalanche ruggedness, the VBM1602 builds upon this foundation for greater efficiency. Based on the same 60V drain-source voltage and industry-standard TO-220 package, it delivers key improvements:
Lower On-Resistance: The VBM1602 achieves a remarkably low on-resistance (RDS(on)) of 2.1mΩ at a 10V gate drive, outperforming the IRFB7534PBF's 2.4mΩ. This reduction directly translates to lower conduction losses and cooler operation.
Higher Current Capability: With a continuous drain current rating of 270A, the VBM1602 offers significantly greater current headroom compared to the 232A of the IRFB7534PBF. This provides enhanced design flexibility and robustness for handling peak currents and demanding thermal conditions.
Quantifiable Performance Gain: According to the conduction loss formula P = I² x RDS(on), at a high load current of 100A, the VBM1602 reduces power dissipation, leading to improved system efficiency and potentially simpler thermal management.
Where It Excels: Application Benefits
The technical strengths of the VBM1602 deliver tangible advantages in its core applications:
Motor Drive Systems: For high-power brushed and brushless DC motor drives in industrial automation, robotics, and automotive systems, the lower RDS(on) minimizes heat generation during startup, stall, and high-torque operations. This results in higher efficiency, improved reliability, and extended system lifespan.
Power Conversion & Switching: In high-current DC-DC converters, inverters, and power stages, the combination of ultra-low on-resistance and high current rating supports more compact, higher-power-density designs with reduced energy loss.
The Strategic Value: Performance & Supply Chain Resilience
Selecting the VBM1602 benefits both your technical design and your supply chain strategy.
Guaranteed Performance Parity or Superiority: The datasheet confirms it meets or exceeds key specifications of the IRFB7534PBF, ensuring a smooth and low-risk design transition.
Mitigate Supply Chain Risk: Sourcing from a leading Chinese manufacturer like VBsemi diversifies your supply base. This provides 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 VBM1602 is more than an alternative; it's a forward-looking component choice for the global market. It delivers the proven ruggedness required to replace the IRFB7534PBF confidently, adds measurable efficiency improvements, and comes with the strategic advantages of a diversified, resilient supply chain.
For your next-generation high-current motor drive, power conversion, or switching design, evaluating the VBM1602 isn't just about finding a substitute—it's about upgrading to a smarter, more powerful, and more sustainable solution.
