Introduction
Power MOSFETs serve as critical switches managing energy flow in modern electronics. For years, international brands like Littelfuse IXYS have led the market with established products such as the IXTP28P065T. 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 VBM2658, domestic components are now achieving direct对标and even surpassing international benchmarks.
Part 1: Analysis of the Classic Component
Littelfuse IXYS's IXTP28P065T is a P-channel MOSFET with a drain-source voltage of 65V, continuous drain current of 28A, and an on-resistance of 45mΩ at 10V and 14A. It utilizes advanced technology to balance voltage tolerance and conduction losses, commonly used in applications like power management, motor drives, and industrial controls, making it a preferred choice for many designs.
Part 2: Performance Surpassing by the Domestic Challenger
VBsemi's VBM2658 directly对标s the IXTP28P065T and demonstrates enhancements in key areas:
Higher Current Capability: Continuous drain current reaches -45A (an increase of 17A), enabling greater power handling and system robustness.
Optimized Conduction Loss: On-resistance is 48mΩ at 10V, closely matching the classic component while supporting improved efficiency in various operating conditions.
Full Compatibility: Features a pin-compatible TO-220 package, allowing seamless replacement without PCB redesign.
The device leverages mature Trench technology, ensuring stable and reliable performance across diverse environments.
Part 3: Core Value Beyond Specifications
Opting for a domestic alternative delivers deeper benefits:
Supply Chain Resilience: Reduces reliance on single-source international suppliers, ensuring stable availability and production continuity.
Cost Efficiency: Offers competitive pricing with comparable or superior performance, potentially lowering overall system costs and enabling peripheral optimizations.
Rapid Local Support: Domestic providers facilitate agile technical assistance and collaborative development tailored to specific application needs.
Industrial Ecosystem Growth: Each successful adoption strengthens the domestic semiconductor sector, fostering experience accumulation and technological iteration for a virtuous cycle.
Part 4: A Robust Path for Substitution Implementation
To ensure a smooth transition, follow these steps:
Detailed Parameter Comparison: Scrutinize all electrical specifications and characteristic curves.
Rigorous Laboratory Testing: Conduct static and dynamic tests, temperature rise assessments, and reliability stress evaluations.
Pilot Batch Verification: Test the component in real-world products and environments, monitoring long-term performance.
Develop a Switchover Plan: Gradually implement the substitution post-verification, while retaining the original design as a short-term backup.
Conclusion: Moving from "Usable" to "Excellent"
The progression from the IXTP28P065T to the VBM2658 underscores that domestic power semiconductors now rival 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 future. Now is the time to actively evaluate and integrate quality domestic solutions.
