Introduction
Power MOSFETs are essential components in modern electronics, acting as critical switches for energy control. For years, international brands like Nexperia have led the market with established products such as the PSMN2R2-25YLC,115. However, global supply chain uncertainties and the drive for technological self-reliance make finding reliable, high-performance domestic alternatives a strategic imperative. Represented by VBsemi's VBED1303, domestic components are now achieving direct对标 and even surpassing international benchmarks.
Part 1: Analysis of the Classic Component
Nexperia's PSMN2R2-25YLC,115 is a logic-level enhanced N-channel MOSFET with a drain-source voltage of 25V and a continuous drain current of 100A. It features a low on-resistance of 2.4mΩ at 10V and 25A, utilizing LFPAK packaging for efficient thermal and electrical performance. This device is designed for a wide range of industrial, communication, and household applications, offering a balance of power handling and reliability.
Part 2: Performance Surpassing by the Domestic Challenger

Part 4: A Robust Path for Substitution Implementation
For a smooth transition, follow these steps:
Detailed Specification Comparison: Carefully review all electrical parameters, including VDS, ID, RDS(on), and characteristic curves.
Rigorous Laboratory Testing: Conduct static parameter tests, dynamic switching evaluations, thermal performance assessments, and reliability stress tests.
Small-Batch Pilot Verification: Trial the component in actual products and environments, monitoring long-term behavior and compatibility.
Develop a Switchover and Backup Plan: Implement the substitution gradually after verification, while retaining the original design as a short-term contingency.
Conclusion: Moving from "Usable" to "Excellent"
The evolution from PSMN2R2-25YLC,115 to VBED1303 illustrates that domestic MOSFETs are capable of competing with and surpassing international classics in key aspects. Adopting such high-performance domestic components is not only a pragmatic solution to supply chain challenges but also a strategic move towards building an autonomous, resilient, and innovative industrial ecosystem for the future. Now is the opportune moment to actively evaluate and integrate quality domestic solutions like VBED1303.
