Introduction
Power MOSFETs are the crucial "switches" controlling energy flow in modern electronic devices. For a long time, international brands like Infineon have dominated the market with their advanced products, such as the IPL65R195C7. However, global supply chain volatility and the need for technological autonomy have made seeking reliable, high-performance domestic alternatives a strategic necessity. Represented by VBsemi's VBQE165R20S, domestic components are now achieving direct对标and even surpassing international classics.
Part 1: Analysis of the Classic Component
Infineon's IPL65R195C7 is a high-voltage MOSFET (650V, 8A) utilizing CoolMOS C7 technology based on the superjunction (SJ) principle. This revolutionary technology offers high efficiency, low gate charge, ease of implementation, and excellent reliability through fast-switching SJ MOSFET design. It is widely used in applications requiring high performance, such as power supplies, industrial systems, and automotive electronics, serving as a benchmark in the field.
Part 2: Performance Surpassing by the Domestic Challenger
VBsemi's VBQE165R20S directly对标s the IPL65R195C7 and offers improvements in key parameters:
Higher Current Handling: Continuous drain current reaches 20A (an increase of 12A), enabling greater power delivery and load capacity.
Lower Conduction Loss: Typical on-resistance is 160mΩ at 10V (compared to 195mΩ), reducing conduction losses and enhancing system efficiency.
Advanced Technology: Employs SJ_Multi-EPI technology, ensuring robust performance and reliability in high-voltage applications.
Package Compatibility: Uses a DFN8X8 package, suitable for space-constrained designs and facilitating seamless replacement in many circuits.
Part 3: Core Value Beyond Specifications
Choosing a domestic alternative brings deeper advantages:
Ensuring Supply Chain Security: Reduces reliance on international suppliers, mitigating risks and ensuring stable production continuity.
Optimizing Overall Cost: Often provides better cost-effectiveness with superior performance, allowing for potential savings in thermal management or peripheral components.
Accessing Rapid Local Support: Domestic manufacturers offer agile technical assistance and customized solutions tailored to specific application needs.
Boosting the Industrial Ecosystem: Each successful substitution strengthens the domestic semiconductor industry, fostering innovation and a virtuous cycle of development.
Part 4: A Robust Path for Substitution Implementation
For a smooth transition, the following steps are recommended:
Detailed Specification Comparison: Carefully review all electrical parameters, including VDS, ID, RDS(on), and switching characteristics.
Rigorous Laboratory Testing: Conduct static and dynamic tests, efficiency evaluations, temperature rise analyses, and reliability stress tests under real-world conditions.
Small-Batch Pilot Verification: Deploy the component in actual products to validate long-term performance and compatibility.
Develop a Switchover and Backup Plan: Implement the substitution gradually after successful verification, while keeping the original design as a temporary backup to minimize disruption.
Conclusion: Moving from "Usable" to "Excellent"
The evolution from the IPL65R195C7 to the VBQE165R20S demonstrates that domestic power semiconductors now compete with and surpass international leaders in key areas. Adopting such high-performance domestic components is a practical response to supply chain challenges and 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 like the VBQE165R20S.
