In various efficient power management application scenarios such as portable devices, battery protection circuits, load switches, and DC-DC converters, Diodes' DMC3061SVTQ-7, with its dual N+P channel configuration and design that balances low on-resistance with superior switching performance, has been a key component for engineers worldwide. However, in the context of global supply chain uncertainties and trade volatility, this imported part increasingly reveals pain points: extended lead times, cost vulnerabilities, and delayed technical support, which constrain production flexibility and cost optimization for downstream companies. This growing industry demand is turning domestic substitution from an "alternative" into a "imperative," serving as a critical path for enterprises to secure supply chains, reduce costs, and enhance product competitiveness.
Leveraging its deep expertise in power semiconductors, VBsemi introduces the VB5460 dual N+P channel MOSFET based on independent R&D. This product is precisely tailored as a direct alternative to the DMC3061SVTQ-7, offering core advantages of enhanced parameters, technological excellence, and full package compatibility. It enables a drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported high-performance solution for modern power management systems.
Comprehensive Parameter Advancement, Delivering Higher Performance and Efficiency.
Designed as a superior domestic alternative to the DMC3061SVTQ-7, the VB5460 achieves significant, leapfrog improvements in key electrical parameters, providing stronger performance guarantees for power management applications:
Firstly, the drain-source voltage rating is increased to ±40V, substantially higher than the original model’s 30V—a 33% improvement. This offers a greater safety margin in applications with voltage spikes or higher bus voltages, enhancing system robustness and reliability.
Secondly, the continuous drain current is boosted to 8A (N-channel) and -4A (P-channel), markedly surpassing the original model’s 2.7A and 3.4A. This increased current-carrying capability supports higher power loads and more demanding applications with ease.
Thirdly, the on-state resistance is significantly reduced, with RDS(on) as low as 30mΩ (@10V, N-channel) and 70mΩ (@10V, P-channel), outperforming the DMC3061SVTQ-7’s 95mΩ and 60mΩ. This reduction directly lowers conduction losses, improves overall efficiency, and minimizes heat generation—critical for compact, high-efficiency designs.
Moreover, the VB5460 supports a ±20V gate-source voltage, enhancing gate robustness against ESD and noise in challenging electromagnetic environments. The optimized gate threshold voltage (1.8V / -1.7V) ensures reliable switching and compatibility with mainstream driver ICs, simplifying design integration and lowering the substitution barrier.
Enhanced with Advanced Trench Technology, Reliability and Switching Performance Optimized.
The DMC3061SVTQ-7 is recognized for its low RDS(on) and good switching characteristics. The VB5460 employs advanced Trench technology, building upon these strengths while further optimizing device reliability and performance. Through meticulous design, the VB5460 achieves an excellent balance between low on-resistance and fast switching, reducing both conduction and switching losses. It is engineered to handle high-frequency operation efficiently, making it ideal for modern switched-mode power supplies and management circuits. Additionally, the device features a robust operating temperature range and undergoes rigorous reliability testing, including high-temperature and high-humidity aging tests, ensuring long-term stability and a lower failure rate than industry averages. This makes it particularly suitable for applications demanding high reliability, such as portable electronics, industrial controls, and automotive power systems.
Fully Compatible Package, Enabling Seamless Drop-In Replacement.
A primary concern in component substitution is the engineering effort and cost involved. The VB5460 addresses this seamlessly through its package design. The device comes in a standard SOT23-6 package, which is pin-to-pin and footprint compatible with the DMC3061SVTQ-7. Engineers can replace the original component without any changes to the PCB layout, thermal design, or assembly process, achieving true plug-and-play convenience. This high degree of compatibility drastically reduces verification time—sample validation can typically be completed within days—and eliminates costs associated with redesign, re-tooling, or re-certification. It allows enterprises to swiftly adopt the alternative, shorten supply cycles, and capture market opportunities with minimal risk.
Local Strength Assurance, Dual Peace of Mind for Supply and Support.
Compared to imported components subject to logistics delays, trade policies, and currency fluctuations, VBsemi leverages a localized semiconductor supply chain with modern manufacturing and R&D facilities in China. This ensures stable mass production and reliable supply of the VB5460, with standard lead times compressed to weeks and expedited options available. Such responsiveness mitigates risks from global volatility and geopolitical factors, safeguarding production schedules. As a domestic brand, VBsemi also provides dedicated, responsive technical support: comprehensive documentation—including substitution guides, datasheets, and application notes—complements scenario-specific design advice. A professional technical team offers rapid, often within 24 hours, assistance for any substitution or design challenges, eliminating the slow response and high communication costs often associated with overseas suppliers. This makes the substitution process smooth, efficient, and worry-free.
From portable device power management and battery protection to load switches, DC-DC converters, and various low-voltage power applications, the VB5460, with its core advantages of “superior parameters, enhanced reliability, package compatibility, secure supply, and attentive support,” has become the preferred domestic alternative to the DMC3061SVTQ-7. It has already been adopted by leading companies across multiple sectors, earning strong market recognition. Choosing the VB5460 is more than a simple component swap—it is a strategic step toward securing your supply chain, optimizing costs, and boosting product competitiveness, all while gaining better performance, stable availability, and immediate technical support without assuming redesign risks.
