In various low-voltage, high-current application scenarios such as DC-DC converters, motor drives, power tools, battery management systems, and server power supplies, Nexperia's PSMN6R5-25YLC,115, with its low on-resistance and high current capability, has been a key choice for engineers worldwide during design selection. However, in the context of global supply chain uncertainties and trade dynamics, this imported component faces challenges: extended lead times, cost volatility, and sometimes delayed technical support. These issues can impact production schedules and cost efficiency. This industry demand makes domestic substitution a strategic necessity, crucial for ensuring supply chain resilience, optimizing costs, and enhancing core competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBED1303 N-channel power MOSFET based on independent R&D. This product is a precise domestic alternative to the PSMN6R5-25YLC,115, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It serves as a direct replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for various high-performance electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Headroom for Demanding Conditions.
Tailored as a domestic alternative, the VBED1303 achieves significant, leapfrog improvements in key electrical parameters, providing robust performance guarantees for low-voltage, high-current applications:
Firstly, the drain-source voltage is increased to 30V, 5V higher than the original model's 25V—a 20% improvement. This offers a greater safety margin in applications with potential voltage spikes or transients, enhancing system reliability.
Secondly, the continuous drain current is dramatically increased to 90A, significantly surpassing the original model's 64A—a over 40% enhancement in current-carrying capability. This enables support for higher power loads and improves operational stability in demanding circuits.
Thirdly, the on-state resistance is as low as 2.8mΩ (@10V gate drive), substantially superior to the PSMN6R5-25YLC,115's 6.5mΩ. This over 55% reduction in RDS(on) significantly lowers conduction losses, directly improving system efficiency and reducing heat generation, which alleviates thermal management design pressure.
Additionally, the VBED1303 supports a ±20V gate-source voltage, ensuring strong gate robustness against ESD and noise. The 0.8V gate threshold voltage design offers optimized switching characteristics, compatible with mainstream driver ICs without requiring drive circuit adjustments, facilitating easy substitution.
Enhanced with Advanced Trench Technology, Delivering Superior Efficiency and Reliability.
The PSMN6R5-25YLC,115 is recognized for its low on-resistance. The VBED1303 employs advanced Trench technology, building upon excellent switching performance while optimizing device reliability. It features ultra-low conduction and switching losses, making it ideal for high-frequency switching applications. The device is designed for high robustness, capable of withstanding harsh electrical environments. Furthermore, it operates over a wide temperature range and has undergone rigorous reliability testing, ensuring long-term, stable operation—suitable for critical applications including automotive, industrial, and communication systems.
Fully Compatible Package, Enabling Seamless, Risk-Free Replacement.
A core concern for domestic substitution is the engineering effort required. The VBED1303 addresses this through its package design. The device uses an LFPAK56 package, which is fully compatible with the PSMN6R5-25YLC,115's package in terms of pinout, dimensions, and footprint. Engineers can achieve a "drop-in" replacement without modifying the PCB layout or thermal design. This high compatibility reduces verification time and cost, eliminates need for redesign, and avoids additional certification processes, allowing enterprises to implement substitution quickly and capture market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply and Support.
Compared to potential supply chain disruptions with imported components, VBsemi leverages a robust domestic semiconductor ecosystem, with modern production and R&D facilities in China. This ensures full-process control and stable mass production of the VBED1303. Lead times are significantly shorter and more predictable, mitigating risks related to international logistics, tariffs, or geopolitics, and securing production plans. As a local provider, VBsemi offers dedicated technical support: providing comprehensive documentation including substitution guides, datasheets, and application notes, plus tailored selection advice and circuit optimization. The technical team promises rapid response, effectively solving the slow support and high communication cost pain points often associated with imported components, making the substitution process smooth and reliable.
From DC-DC converters and motor drives to power tools and server PSUs; from battery management and UPS to various low-voltage power switching applications, the VBED1303, with its core advantages of "superior parameters, higher efficiency, package compatibility, secure supply, and responsive service," has become the preferred domestic alternative to the PSMN6R5-25YLC,115. It has gained successful applications and high market recognition across multiple industries. Choosing the VBED1303 is not just a simple component replacement; it is a strategic step for enterprises to enhance supply chain security, optimize costs, and boost product competitiveness—requiring no R&D modification risk while benefiting from better performance, more stable supply, and more convenient local support.
