Introduction
Power MOSFETs are the crucial "switches" controlling energy flow in modern electronic devices. For a long time, international brands like ROHM have dominated the market with their classic products, such as the R6024ENJTL. 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 VBL16R20S, domestic components are now achieving direct对标and even surpassing international classics.
Part 1: Analysis of the Classic Component
ROHM's R6024ENJTL is a high-voltage MOSFET (600V, 24A) featuring low on-resistance (165mΩ@10V). This device is designed for high-power applications including industrial power supplies, motor drives, and energy systems, offering robust performance and reliability that have made it a preferred choice in many designs.
Part 2: Performance Surpassing by the Domestic Challenger
VBsemi's VBL16R20S directly对标s the R6024ENJTL and delivers enhancements in critical areas:
Advanced Technology: Employs SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology, enabling superior switching performance, reduced switching losses, and improved thermal efficiency compared to traditional planar processes.
Robust Voltage Handling: Drain-source voltage maintains 600V with a wide gate-source voltage range of ±30V, ensuring operational stability and safety margins in demanding environments.
Optimized Design Balance: While the continuous drain current is rated at 20A and on-resistance is 190mΩ@10V, the device achieves an optimal trade-off between conduction loss and switching speed, potentially enhancing overall system efficiency in dynamic applications.
Full Compatibility: Offered in a TO263 package, it provides pin-to-pin compatibility, allowing seamless replacement without PCB layout changes.
Part 3: Core Value Beyond Specifications
Selecting a domestic alternative like VBL16R20S unlocks deeper advantages:
Ensuring Supply Chain Security: Reduces reliance on international supply chains, mitigating risks and ensuring consistent availability for production.
Optimizing Total Cost of Ownership: Often provides better cost-effectiveness with competitive performance, enabling savings in system design and maintenance.
Accessing Rapid Local Support: Domestic suppliers offer responsive technical assistance, faster logistics, and tailored solutions for specific application needs.
Boosting the Industrial Ecosystem: Each successful adoption strengthens the domestic semiconductor sector, fostering innovation and a sustainable technology cycle.
Part 4: A Robust Path for Substitution Implementation
To ensure a smooth transition, follow these steps:
Detailed Specification Comparison: Review all key parameters, including VDS, ID, RDS(on), Vth, and switching characteristics under typical operating conditions.
Rigorous Laboratory Testing: Conduct static parameter validation, dynamic switching tests, thermal performance assessments, and long-term reliability stress tests.
Small-Batch Pilot Verification: Deploy the component in actual products or prototypes, monitoring real-world performance and compatibility over time.
Develop a Switchover and Backup Plan: Gradually implement the substitution after successful verification, while retaining the original design as a temporary backup to minimize disruption.
Conclusion: Moving from "Usable" to "Excellent"
The evolution from R6024ENJTL to VBL16R20S demonstrates that domestic power semiconductors are capable of competing with and exceeding international benchmarks through technological innovation and strategic design. Adopting such high-performance domestic components is not only a practical response to supply chain challenges but also a forward-looking step toward building an autonomous, resilient, and innovative industrial future. Now is the opportune moment to actively evaluate and integrate these advanced domestic solutions.
