Introduction
Power MOSFETs serve as essential "switches" managing energy flow in modern electronics. For years, international brands like Nexperia have led the market with established products such as the BUK9Y15-60E,115. However, global supply chain uncertainties and the pursuit of technological self-reliance have made finding reliable, high-performance domestic alternatives a strategic imperative. Represented by VBsemi's VBED1606, domestic components are now achieving direct benchmarking and even surpassing international classics.
Part 1: Analysis of the Classic Component
Nexperia's BUK9Y15-60E,115 is a low-voltage MOSFET (60V, 53A) known for its robust performance in high-current applications. With a threshold voltage of 2.1V, it offers efficient switching and is widely used in automotive systems, power management, and industrial controls, becoming a trusted choice for many designs.
Part 2: Performance Surpassing by the Domestic Challenger
VBsemi's VBED1606 directly benchmarks the BUK9Y15-60E,115 and delivers enhancements in key parameters:
Higher Current Capacity: Continuous drain current reaches 64A (an increase of 11A), enabling greater power handling and reliability.
Lower Conduction Loss: Typical on-resistance (RDS(10V)) is 6.2 mΩ, significantly reducing conduction losses and improving system efficiency.
Wide Threshold Range: Threshold voltage (Vth) spans 1~3V, offering design flexibility and compatibility.
Full Compatibility: Uses a pin-compatible LFPAK56 package, allowing direct replacement without PCB modifications.
The device leverages advanced Trench technology, ensuring fast switching and stable performance.
Part 3: Core Value Beyond Specifications
Opting for a domestic alternative provides deeper advantages:
Ensuring Supply Chain Security: Reduces reliance on single international sources, guaranteeing supply stability and production continuity.
Optimizing Overall Cost: Typically offers better cost-effectiveness with comparable or superior performance, potentially simplifying peripheral designs like cooling solutions.
Accessing Rapid Local Support: Domestic suppliers enable agile technical support and tailored joint development for specific application needs.
Boosting the Industrial Ecosystem: Each successful application helps the domestic semiconductor industry gain experience and iterate technology, fostering a virtuous cycle of innovation.
Part 4: A Robust Path for Substitution Implementation
For a seamless transition, follow these steps:
Detailed Specification Comparison: Carefully compare all 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, monitoring long-term performance.
Develop a Switchover and Backup Plan: Gradually implement the substitution after verification, while keeping the original design as a short-term backup.
Conclusion: Moving from "Usable" to "Excellent"
The progression from the BUK9Y15-60E,115 to the VBED1606 illustrates that domestic power semiconductors now possess the capability to rival and exceed international classics in key aspects. 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 ecosystem for the future. Now is the ideal time to actively evaluate and integrate quality domestic solutions.
