In various low-voltage, high-current application scenarios such as DC-DC converters, motor drives, power tools, automotive systems, and server power supplies, Nexperia's PSMN4R1-60YLX, with its advanced TrenchMOS technology, low on-resistance, and high current capability, has long been a significant choice for engineers worldwide during design selection. However, against the backdrop of intensified global supply chain disruptions and frequent international trade frictions in the post-pandemic era, this imported component has gradually exposed numerous pain points: unstable lead times, procurement costs susceptible to exchange rate fluctuations, and lagging technical support responses. These issues severely constrain downstream companies' production schedules and cost control. Given this industry demand, domestic substitution has transitioned from an "option" to a "necessity," becoming a critical path for enterprises to ensure supply chain security, reduce costs, enhance efficiency, and improve core competitiveness.
VBsemi, with years of deep cultivation in the power semiconductor field, has launched the VBED1603 N-channel power MOSFET based on its independent R&D capabilities. This product precisely对标es the PSMN4R1-60YLX, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It can serve as a direct replacement without any modifications to the original circuit, providing a more stable, cost-effective, and locally attuned high-quality solution for various low-voltage high-current electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the PSMN4R1-60YLX, the VBED1603 achieves across-the-board, leapfrog improvements in key electrical parameters, offering more robust performance guarantees for high-current applications:
Firstly, the drain-source voltage is maintained at 60V, matching the original model's 60V, ensuring seamless compatibility in low-voltage applications and providing reliable operation in automotive and industrial environments with strict voltage requirements.
Secondly, the continuous drain current is maintained at 100A, matching the original model's 100A, ensuring high current-carrying capability for power-intensive designs without compromise.
Thirdly, the on-state resistance is as low as 2.9mΩ (@10V gate drive), significantly superior to the PSMN4R1-60YLX's 4.8mΩ (@5V, 25A). This reduction in conduction losses directly contributes to improved system efficiency, reducing heat generation and lowering cooling system demands, which is critical for high-density power designs.
Additionally, the VBED1603 supports a ±20V gate-source voltage, offering strong gate ESD and noise immunity, effectively preventing unintended turn-on in complex electromagnetic environments. The 2.4V gate threshold voltage design balances driving convenience and switching reliability, perfectly matching mainstream driver ICs on the market without requiring additional adjustments to the drive circuit, further lowering the barrier to substitution.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the PSMN4R1-60YLX lies in the low on-resistance and high efficiency brought by its TrenchMOS technology. The VBED1603 employs the industry-leading Trench gate process, building upon the excellent switching characteristics of the original model while optimizing device reliability across multiple dimensions. The device undergoes rigorous testing and screening before leaving the factory, exhibiting excellent thermal and electrical performance. It can easily handle high current surges and fast switching transitions, significantly reducing the risk of device failure. Through optimized intrinsic capacitance structure design, it not only reduces charge/discharge losses during switching but also elevates dv/dt tolerance to a higher level, perfectly matching the application scenarios of the PSMN4R1-60YLX. Even under harsh conditions like high-frequency switching and high current transients, it maintains stable operation and can be directly replaced without modifying the circuit topology. Furthermore, the VBED1603 features a wide operating temperature range, capable of adapting to various complex working conditions such as automotive under-hood environments and industrial high-temperature settings. Having passed extensive reliability tests, its failure rate is far below the industry average, providing solid assurance for long-term, uninterrupted equipment operation—especially suitable for critical fields with reliability requirements like automotive electronics, industrial control, and power management systems.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a core concern regarding domestic substitution is the R&D investment and time costs involved in the replacement process. The VBED1603 fundamentally addresses this pain point through its package design. The device uses an LFPAK56 package, which is completely identical to the PSMN4R1-60YLX's LFPAK56 package in terms of pinout, pin spacing, package dimensions, and thermal characteristics. Engineers need not make any modifications to the original PCB layout or adjust the thermal system design, achieving a "plug-and-play" convenient replacement. The advantages brought by this high degree of compatibility are evident: on one hand, it significantly reduces the time cost of substitution verification, eliminating the need for R&D teams to invest in circuit redesign, simulation, and testing—sample validation can typically be completed within 1-2 days. On the other hand, it avoids increased production costs from PCB revisions and mold adjustments while ensuring the original product's structural dimensions remain unchanged, eliminating the need for re-certification and外观 design. This effectively shortens the supply chain cycle, helping enterprises quickly achieve the substitution and upgrade of imported components and seize market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to the unstable supply chain of imported components affected by multiple factors like international logistics, trade policies, and exchange rate fluctuations, VBsemi leverages China's well-established semiconductor industry chain layout, with modern production bases and R&D centers in Jiangsu, Guangdong, and other locations. This enables full-process independent R&D and stable mass production of the VBED1603. Currently, the standard lead time for this model is compressed to within 2 weeks, with emergency orders enabling 72-hour rapid delivery. This effectively mitigates various risks such as international supply chain volatility, tariff barriers, and geopolitics, providing solid assurance for the smooth progress of enterprise production plans. Simultaneously, as a local brand, VBsemi boasts a professional technical support team offering "one-on-one" customized services: not only providing comprehensive technical documentation, including detailed substitution验证 reports, device datasheets, thermal design guides, and application circuit references, but also offering targeted selection advice and circuit optimization solutions based on specific customer application scenarios. For any technical issues arising during the substitution process, the technical team can provide rapid response within 24 hours, assisting with on-site or remote resolution. This彻底addresses the pain points of slow technical support response and high communication costs associated with imported components, making the substitution process smoother and more worry-free.
From DC-DC converters and motor drives to power tools and automotive systems; from server power supplies and battery management to industrial automation and renewable energy applications, the VBED1603, with its core advantages of "superior parameters, more stable performance, package compatibility, controllable supply, and attentive service," has become the preferred solution for domestic substitution of the PSMN4R1-60YLX. It has already achieved application in several leading companies across multiple industries, receiving high market recognition. Choosing the VBED1603 is not merely a simple component replacement; it is a crucial step for enterprises in upgrading supply chain security, optimizing production costs, and enhancing product competitiveness—requiring no assumption of R&D modification risks while enjoying superior performance, more stable supply, and more convenient technical support.
