Introduction
Power MOSFETs serve as the critical "switches" managing energy flow in modern electronics. For years, international giants like ROHM have led the market with established products such as the R6035ENZ4C13. However, global supply chain disruptions and the pursuit of technological self-reliance have made finding reliable, high-performance domestic alternatives a strategic imperative. Represented by VBsemi's VBP165R36S, domestic components are now achieving direct对标and even surpassing international benchmarks.
Part 1: Analysis of the Classic Component
ROHM's R6035ENZ4C13 is a high-voltage MOSFET (600V, 35A) featuring optimized design for low on-resistance (102mΩ@10V). It offers robust performance and reliability, commonly employed in high-power applications like industrial power supplies, motor drives, and energy systems, serving as a preferred solution in many designs.
Part 2: Performance Surpassing by the Domestic Challenger
VBsemi's VBP165R36S directly对标s the R6035ENZ4C13 and demonstrates enhancements in key specifications:
Superior Voltage and Current Ratings: Drain-source voltage reaches 650V (a 50V increase), and continuous drain current attains 36A (a 1A increase), delivering a wider safety margin and enhanced power handling.
Reduced Conduction Loss: Typical on-resistance is 75mΩ@10V, significantly lower than the classic, minimizing conduction losses and boosting system efficiency.
Full Compatibility: Utilizes a pin-compatible TO-247 package, enabling seamless replacement without PCB redesign.
The device leverages advanced SJ_Multi-EPI technology, ensuring high performance and stability.
Part 3: Core Value Beyond Specifications
Opting for this domestic alternative extends deeper benefits:
Ensuring Supply Chain Resilience: Mitigates reliance on singular international sources, safeguarding supply stability and production continuity.
Optimizing Total Cost: Offers competitive pricing with superior parameters, potentially simplifying peripheral designs (e.g., cooling systems).
Accessing Agile Local Support: Domestic suppliers provide responsive technical assistance and customized solutions for real-world applications.
Strengthening the Industrial Ecosystem: Each successful adoption fuels experience accumulation and technological iteration in domestic semiconductors, fostering a virtuous cycle.
Part 4: A Robust Path for Substitution Implementation
To ensure a smooth transition, follow these steps:
Detailed Specification Comparison: Scrutinize all key electrical parameters and characteristic curves.
Rigorous Laboratory Testing: Perform static parameter checks, dynamic switching tests, thermal/efficiency evaluations, and reliability stress tests.
Small-Batch Pilot Verification: Trial the component in actual products and environments, monitoring long-term performance.
Develop a Switchover and Backup Plan: Gradually implement the substitution post-verification, while retaining the original design as a short-term backup.
Conclusion: Moving from "Usable" to "Excellent"
The progression from the R6035ENZ4C13 to the VBP165R36S illustrates that domestic power semiconductors now rival and exceed international classics in key areas. Adopting such high-performance domestic components is not only a practical response to supply chain challenges but also a strategic step toward building an autonomous, resilient, and innovative industrial future. Now is the time to actively evaluate and integrate premium domestic solutions.
