Introduction
Power MOSFETs serve as essential switches for energy control in modern electronics. For years, international brands like RENESAS have led the market with established products such as the UPA2756GR-E1-AT. However, global supply chain disruptions and the pursuit of technological self-reliance have made finding reliable, high-performance domestic alternatives a strategic priority. Represented by VBsemi's VBA3610N, domestic components are now achieving direct对标and even surpassing international benchmarks.
Part 1: Analysis of the Classic Component
RENESAS's UPA2756GR-E1-AT is a dual N-channel MOSFET with a drain-source voltage of 60V and a continuous drain current of 4A. It features an on-resistance of 150mΩ at 4.0V gate drive, balancing performance and reliability for medium- to low-power applications like power management, motor drives, and consumer electronics, making it a common choice in many designs.
Part 2: Performance Surpassing by the Domestic Challenger
VBsemi's VBA3610N directly对标s the UPA2756GR-E1-AT and demonstrates improvements in key areas:
Lower Conduction Loss: With an on-resistance of 110mΩ at 10V gate drive (compared to 150mΩ at 4.0V), it reduces conduction losses and enhances system efficiency.
Robust Voltage and Current Ratings: Maintains 60V drain-source voltage and 4A continuous drain current, ensuring compatibility while offering a wider gate-source voltage range of ±20V.
Full Compatibility: Uses a pin-compatible SOP8 package with a dual N-channel configuration, enabling drop-in replacement without PCB redesign.
Advanced Technology: Built on Trench process technology, it delivers stable and efficient switching performance.
Part 3: Core Value Beyond Specifications
Opting for a domestic alternative provides deeper benefits:
Supply Chain Security: Reduces reliance on single international sources, ensuring stable supply and production continuity.
Cost Optimization: Often offers better cost-effectiveness with comparable or superior performance, allowing potential savings in peripheral design.
Rapid Local Support: Domestic suppliers can provide agile technical assistance and customized solutions for specific application needs.
Ecosystem Growth: Each successful adoption helps the domestic semiconductor industry gain experience and drive innovation, fostering a virtuous development cycle.
Part 4: A Robust Path for Substitution Implementation
To ensure a smooth transition, follow these steps:
Detailed Specification Comparison: Review all electrical parameters and characteristic curves.
Rigorous Laboratory Testing: Conduct static and dynamic tests, thermal performance evaluations, and reliability stress tests.
Small-Batch Pilot Verification: Trial the component in real-world products and environments, monitoring long-term behavior.
Develop a Switchover and Backup Plan: Implement substitution gradually after validation, while keeping the original design as a short-term backup.
Conclusion: Moving from "Usable" to "Excellent"
The shift from the UPA2756GR-E1-AT to the VBA3610N illustrates that domestic power semiconductors can now compete with and exceed international classics in key aspects. Embracing 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.
