Introduction
Power MOSFETs serve as critical switches managing energy flow in modern electronics. For years, international brands like RENESAS have set market standards with proven components such as the 2SJ172-E. However, global supply chain uncertainties and the push for technological self-reliance have made finding reliable, high-performance domestic alternatives a strategic imperative. Represented by VBsemi's VBM2610N, local solutions now offer direct competition and even outperformance of classic international parts.
Part 1: Analysis of the Classic Component
RENESAS's 2SJ172-E is a power MOSFET rated for 60V drain-source voltage and 10A continuous drain current. It features an on-resistance of 250mΩ at 4V gate drive and a power dissipation of 40W. This component is commonly used in medium-power applications like motor drives, power supplies, and industrial controls, earning a reputation for stability and widespread adoption in various designs.
Part 2: Performance Surpassing by the Domestic Challenger
VBsemi's VBM2610N directly targets the 2SJ172-E and delivers enhancements in key areas:
Superior Current Handling: Continuous drain current reaches 40A (a 30A increase over the 2SJ172-E), enabling higher power throughput and robust performance in demanding circuits.
Reduced Conduction Losses: On-resistance is as low as 62mΩ at 10V gate drive, significantly lower than the 250mΩ of the 2SJ172-E, minimizing heat generation and improving system efficiency.
Enhanced Voltage Tolerance: Drain-source voltage is rated at 60V (matching the classic part), with a gate-source voltage range of ±20V for flexible drive compatibility.
Advanced Technology: Built on a Trench process, the VBM2610N ensures fast switching and reliable operation under stress.
Full Compatibility: Housed in a TO-220 package with pin-for-pin equivalence, it allows drop-in replacement without board redesign.
Part 3: Core Value Beyond Specifications
Opting for this domestic alternative extends benefits beyond raw specs:
Supply Chain Resilience: Reduces reliance on single-source international suppliers, safeguarding production continuity and mitigating geopolitical risks.
Cost Optimization: Offers competitive pricing with superior performance, potentially lowering total system costs through simplified thermal management or peripheral design.
Local Support Agility: Domestic providers like VBsemi enable faster technical assistance, custom solutions, and collaborative development tailored to regional needs.
Industry Ecosystem Growth: Each successful adoption fuels the domestic semiconductor sector, fostering innovation and creating a virtuous cycle of advancement.
Part 4: A Robust Path for Substitution Implementation
To ensure a seamless transition, follow these steps:
Detailed Parameter Comparison: Review all electrical characteristics, including threshold voltage (Vth) and dynamic behavior.
Rigorous Lab Testing: Perform static tests (e.g., on-resistance, leakage current), dynamic switching evaluations, thermal analysis, and long-term reliability checks.
Pilot Batch Validation: Integrate the VBM2610N into actual products for real-world testing, monitoring performance over time.
Switchover and Contingency Planning: Gradually implement the substitution after verification, while keeping the original design as a short-term backup if needed.
Conclusion: Moving from "Usable" to "Excellent"
The shift from the RENESAS 2SJ172-E to VBsemi's VBM2610N illustrates that domestic power semiconductors have reached a stage where they can not only match but exceed international benchmarks in key metrics. Embracing such high-performance local components is both a practical response to supply chain challenges and a strategic step toward building an autonomous, resilient, and innovative industrial future. Now is the time to actively evaluate and deploy superior domestic solutions like the VBM2610N.
