In the pursuit of robust and diversified supply chains, engineers globally are seeking high-performance alternatives to established power components. For those evaluating STMicroelectronics' N-channel MOSFET, the STW28N60M2, we present a compelling high-performance Chinese-designed alternative: VBsemi's VBP16R26S.
This is not just a direct replacement. The VBP16R26S signifies a strategic upgrade, offering enhanced electrical characteristics alongside the stability and cost benefits of a modern, diversified supply source.
Beyond Replacement: A Technical Performance Leap
While the STW28N60M2 is a reliable workhorse with its 600V, 22A rating and MDmesh M2 technology, the VBP16R26S builds upon this foundation for superior performance. Featuring the same 600V drain-source voltage and industry-standard TO-247 package, it delivers critical advancements:
Lower Conduction Losses: A key improvement is the significantly reduced on-resistance (RDS(on)). With a 10V gate drive, the VBP16R26S achieves 115mΩ, a notable reduction compared to the STW28N60M2's 135mΩ. This translates directly into higher system efficiency and reduced thermal dissipation.
Increased Current Capability: The continuous drain current is raised to 26A, providing greater design margin and robustness over the original 22A rating. This offers engineers enhanced flexibility and reliability for handling peak currents or operating in demanding conditions.
Quantifiable Efficiency Gain: Based on the conduction loss formula P = I² x RDS(on), at a typical 15A load, the VBP16R26S reduces power dissipation significantly. This results in cooler operation, potentially simplifying thermal management and boosting overall system longevity.
Where It Excels: Application Benefits
The technical strengths of the VBP16R26S deliver tangible advantages in its target applications:
Switch-Mode Power Supplies (SMPS): In PFC, primary-side switching, or hard-switched topologies, lower RDS(on) and robust current handling improve efficiency and power density, aiding compliance with energy standards.
Motor Drives & Inverters: For industrial motor controls, UPS systems, and solar inverters, the combination of high voltage rating, lower conduction loss, and higher current capability supports more efficient and compact designs.
High-Voltage Power Conversion: Its 600V rating and improved characteristics make it suitable for various AC-DC and DC-DC conversion stages requiring high breakdown voltage and efficiency.
The Strategic Value: Performance & Supply Chain Resilience
Choosing the VBP16R26S benefits both your technical design and supply chain strategy.
Guaranteed Performance Parity (or Better): The datasheet confirms it meets or exceeds key specifications of the STW28N60M2, 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 resilience against geopolitical factors, 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: An Intelligent Choice for Advanced Designs
VBsemi’s VBP16R26S is more than an alternative; it's a forward-looking component choice. It delivers the proven performance to confidently replace the STW28N60M2, adds measurable efficiency improvements, and comes with the strategic advantages of a diversified, resilient supply chain.
For your next-generation high-voltage power supply, motor drive, or industrial power conversion design, evaluating the VBP16R26S isn't just about finding a substitute—it's about upgrading to a smarter, more capable, and sustainable solution.
