Introduction
Power MOSFETs are the crucial "switches" controlling energy flow in modern electronic devices. For a long time, international brands like ROHM have dominated the market with their classic products, such as the R6024KNZ1C9. However, global supply chain volatility and the need for technological autonomy have made seeking reliable, high-performance domestic alternatives a strategic necessity. Represented by VBsemi's VBP16R26S, domestic components are now achieving direct benchmarking and even surpassing international classics.
Part 1: Analysis of the Classic Component
ROHM's R6024KNZ1C9 is a high-voltage MOSFET (600V) with a low on-resistance of 165mΩ@10V,1mA and a high power dissipation of 245W. This device leverages advanced technology to balance voltage withstand capability and conduction loss, making it widely used in high-power applications like industrial power supplies, motor drives, and energy systems, where it serves as a reliable standard for many designs.
Part 2: Performance Surpassing by the Domestic Challenger
VBsemi's VBP16R26S directly benchmarks the R6024KNZ1C9 and offers improvements in key parameters:
Lower Conduction Loss: Typical on-resistance is 115mΩ@10V, significantly reducing conduction losses and enhancing system efficiency.
Higher Current Capacity: Continuous drain current reaches 26A, providing greater power handling capability.
Comparable Voltage Withstand: Drain-source voltage maintains 600V, ensuring matching performance in high-voltage scenarios.
Advanced Technology: Utilizes SJ_Multi-EPI technology, delivering robust and reliable operation.
Full Compatibility: Features a pin-compatible TO-247 package, allowing direct replacement without PCB modifications.
Part 3: Core Value Beyond Specifications
Choosing a domestic alternative brings deeper advantages:
Ensuring Supply Chain Security: Reduces reliance on international supply chains, guaranteeing stability and production continuity.
Optimizing Overall Cost: Offers better cost competitiveness with superior performance, potentially simplifying peripheral designs like thermal management.
Accessing Rapid Local Support: Domestic suppliers provide agile technical support and tailored joint development for application scenarios.
Boosting the Industrial Ecosystem: Each successful application helps the domestic semiconductor industry accumulate experience and iterate technology, fostering a virtuous development cycle.
Part 4: A Robust Path for Substitution Implementation
For a smooth transition, the following steps are recommended:
Detailed Specification Comparison: Carefully compare all key electrical parameters and characteristic curves.
Rigorous Laboratory Testing: Conduct static parameter tests, dynamic switching tests, temperature rise/efficiency tests, and reliability stress tests.
Small-Batch Pilot Verification: Trial the component in real products and environments, tracking long-term performance.
Develop a Switchover and Backup Plan: Implement the substitution gradually after verification, while retaining the original design as a short-term backup.
Conclusion: Moving from "Usable" to "Excellent"
The evolution from the R6024KNZ1C9 to the VBP16R26S demonstrates that domestic power semiconductors now possess the capability to compete with and surpass international classics in key aspects. Adopting such high-performance domestic components is not only a pragmatic response to supply chain challenges but also a strategic move to build an autonomous, resilient, and innovative industrial ecosystem for the future. Now is the opportune time to actively evaluate and introduce high-quality domestic solutions.
