In various low-voltage, high-current application scenarios such as DC-DC converters, motor drives, power management systems, automotive electronics, and server power supplies, Nexperia's PSMN2R9-25YLC,115, with its advanced TrenchMOS technology, low on-resistance, and high current-handling capability, has been a preferred choice for engineers worldwide during design selection. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component increasingly reveals pain points: unpredictable lead times (often extending to months), procurement costs vulnerable to exchange rate swings, and delayed technical support responses. These issues severely impact downstream companies' production schedules and cost efficiency. Given this industry demand, domestic substitution has evolved from an "option" to a "necessity," becoming a critical path for enterprises to ensure supply chain security, reduce costs, and enhance core competitiveness.
VBsemi, leveraging years of expertise in power semiconductors, introduces the VBED1303 N-channel power MOSFET based on independent R&D. This product precisely aligns with the PSMN2R9-25YLC,115, offering core advantages of parameter enhancements, technological parity, and full package compatibility. It serves as a direct drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally attuned solution for various low-voltage electronic systems.
Comprehensive Parameter Advancement, Enhanced Performance Margins, Adapting to Demanding Conditions.
Tailored as a domestic alternative to the PSMN2R9-25YLC,115, the VBED1303 achieves significant improvements in key electrical parameters, providing robust performance for high-current applications:
First, the drain-source voltage is increased to 30V, 5V higher than the original model's 25V—a 20% improvement. This upgrade offers a greater safety margin in environments with voltage spikes or fluctuations, effectively preventing overvoltage-related failures.
Second, the continuous drain current is rated at 90A, slightly below the original model's 100A, but paired with a drastically reduced on-state resistance. The VBED1303 features an RDS(on) of just 2.8mΩ (@10V gate drive), significantly lower than the PSMN2R9-25YLC,115's typical RDS(on) (implied by its "2R9" designation, approximately 2.9mΩ). This reduction minimizes conduction losses, enhancing overall system efficiency and reducing heat generation, which alleviates cooling design pressures.
Third, the gate threshold voltage is optimized to 0.8V, compared to the original's 1.95V. This lower threshold enables easier driving with lower gate voltages, improving switching performance and compatibility with modern low-voltage driver ICs. Additionally, the VBED1303 supports a ±20V gate-source voltage, offering superior gate ESD protection and noise immunity, ensuring reliable operation in noisy electromagnetic environments.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The core strength of the PSMN2R9-25YLC,115 lies in its TrenchMOS technology, delivering low on-resistance and fast switching. The VBED1303 employs state-of-the-art Trench gate process, building upon these attributes while enhancing reliability. The device undergoes rigorous pre-screening and 100% avalanche testing, exhibiting excellent robustness against transient energy surges. Through optimized intrinsic capacitance design, it reduces switching losses and improves dv/dt tolerance, matching the application scenarios of the original model. The VBED1303 operates over a wide temperature range from -55°C to 150°C, suitable for harsh conditions like automotive under-hood or industrial high-temperature environments. It has passed extended reliability tests, including high-temperature/high-humidity aging, ensuring a low failure rate for critical applications such as automotive systems, telecom infrastructure, and industrial automation.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, a key concern in domestic substitution is the cost and effort of redesign. The VBED1303 addresses this seamlessly through package compatibility. The device uses an LFPAK56 package, identical to the PSMN2R9-25YLC,115 in pinout, dimensions, and thermal pad layout. Engineers can replace the component directly without altering PCB layouts or thermal management systems, achieving "plug-and-play" convenience. This compatibility slashes substitution verification time—sample validation can be completed in 1-2 days—and avoids costs associated with PCB revisions or retooling. It ensures unchanged product form factors, eliminating re-certification needs and accelerating time-to-market.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Technical Support.
Compared to imported components plagued by supply chain volatility, VBsemi leverages China's mature semiconductor ecosystem, with modern production bases in Jiangsu and Guangdong, enabling full-process control and stable mass production of the VBED1303. Standard lead times are compressed to under 2 weeks, with expedited orders enabling 72-hour delivery, mitigating risks from international logistics, tariffs, or geopolitics. As a local brand, VBsemi provides dedicated technical support: comprehensive documentation (including substitution verification reports, datasheets, thermal guides, and application notes), plus tailored advice based on customer scenarios. The technical team offers 24-hour rapid response for any substitution issues, resolving problems on-site or remotely. This eliminates the slow support and high communication costs of imported components, making substitution smooth and worry-free.
From DC-DC converters and motor drives to automotive power systems and server PSUs; from battery management and LED drivers to industrial controls and consumer electronics, the VBED1303, with its core advantages of "superior parameters, enhanced reliability, package compatibility, controlled supply, and responsive service," has become the preferred domestic alternative to the PSMN2R9-25YLC,115. It has already seen adoption in leading companies across multiple sectors, gaining strong market recognition. Choosing the VBED1303 is not just a component swap; it is a strategic move for enterprises to upgrade supply chain security, optimize costs, and boost product competitiveness—requiring no R&D redesign risks while benefiting from better performance, stable supply, and local support.
