Introduction
Power MOSFETs serve as the critical "switches" governing energy flow in modern electronics. For a long time, international brands like ROHM have led the market with established products such as the R6024VNXC7G. However, global supply chain fluctuations and the pursuit of technological self-reliance have made finding reliable, high-performance domestic alternatives a strategic imperative. Represented by VBsemi's VBMB165R13S, domestic components are now achieving direct对标and even surpassing international benchmarks.
Part 1: Analysis of the Classic Component
ROHM's R6024VNXC7G is an N-channel high-voltage MOSFET (600V, 13A) featuring low on-resistance (153mΩ @15V, 6A). This device offers a balance of voltage withstand capability and current handling, making it suitable for applications like switching power supplies, motor drives, and industrial controls, where it has become a standard choice in many designs.
Part 2: Performance Surpassing by the Domestic Challenger
VBsemi's VBMB165R13S directly对标s the R6024VNXC7G and demonstrates enhancements in key specifications:
Superior Voltage Rating: Drain-source voltage is increased to 650V, providing a wider safety margin and enhanced robustness in high-voltage scenarios.
Maintained High Current Capacity: Continuous drain current remains at a robust 13A, ensuring equivalent power handling capability.
Optimized Conduction Characteristics: With a gate threshold voltage (Vth) of 3.5V and a gate-source voltage (VGS) range of ±30V, it offers stable and flexible drive compatibility.
Advanced Technology: Built on a mature SJ_Multi-EPI (Super Junction Multi-Epitaxial) process, which contributes to efficient performance.
Full Compatibility: The TO-220F package is pin-to-pin compatible, allowing for direct replacement without circuit board modifications.
Part 3: Core Value Beyond Specifications
Selecting this domestic alternative delivers deeper strategic benefits:
Enhanced Supply Chain Security: Reduces reliance on single-source international suppliers, ensuring greater stability and continuity of production.
Cost Optimization Potential: Offers competitive pricing with comparable or superior performance, enabling potential savings and optimization of peripheral design.
Access to Rapid Local Support: Domestic suppliers provide more responsive technical support and collaborative development tailored to specific application needs.
Strengthening the Industrial Ecosystem: Each successful adoption contributes to the domestic semiconductor industry's experience and technological progression, fostering a virtuous cycle of innovation.
Part 4: A Robust Path for Substitution Implementation
To ensure a smooth transition, the following steps are recommended:
Detailed Parameter Comparison: Meticulously compare all key electrical parameters and characteristic curves under relevant operating conditions.
Comprehensive Laboratory Testing: Perform static parameter verification, dynamic switching tests, thermal/efficiency evaluations, and reliability stress tests.
Small-Batch Pilot Verification: Implement the component in actual products and environments, monitoring long-term performance and stability.
Develop a Phased Switchover Plan: Adopt the substitution gradually upon successful validation, while maintaining the original design as a short-term backup option.
Conclusion: Moving from "Usable" to "Excellent"
The progression from the R6024VNXC7G to the VBMB165R13S illustrates that domestic power semiconductors now possess the capability not only to match but to exceed international classics in key aspects. Adopting such high-performance domestic components is both a practical solution to current supply chain challenges and a strategic investment in building an autonomous, resilient, and innovative industrial ecosystem for the future. Now is the opportune moment to actively evaluate and integrate these quality domestic solutions.
