In various low-voltage, high-current application scenarios such as DC-DC converters, motor drives, power tools, battery management systems, and load switches, Renesas IDT's UPA2706GR-E2-AT, with its low on-resistance, high current handling, and compact SOP8 package, has been a popular choice for engineers in power design. However, in the context of global supply chain uncertainties and the need for cost optimization, this imported component presents challenges: extended lead times, vulnerability to price volatility, and limited local technical support. These factors can hinder production efficiency and increase overall project costs. Consequently, domestic substitution has evolved from an alternative to a strategic imperative, crucial for ensuring supply chain resilience, reducing dependencies, and enhancing product competitiveness.
Leveraging its expertise in power semiconductor design, VBsemi introduces the VBA1311 N-channel MOSFET, developed through independent R&D. This product is designed as a direct counterpart to the UPA2706GR-E2-AT, offering key advantages in parameter optimization, technological parity, and full package compatibility. It serves as a drop-in replacement without requiring circuit modifications, delivering a more cost-effective, readily available, and locally supported solution for various low-voltage electronic systems.
Enhanced Key Parameters, Superior Efficiency, and Robust Performance.
Tailored as a domestic alternative to the UPA2706GR-E2-AT, the VBA1311 achieves significant improvements in critical electrical parameters, providing enhanced performance and reliability for demanding applications:
The drain-source voltage is maintained at 30V, matching the original specification, ensuring suitability for standard low-voltage circuits. The continuous drain current is rated at 13A, offering robust current-carrying capability for a wide range of power applications.
A standout feature is the remarkably low on-state resistance of only 8mΩ (@10V gate drive), which is substantially lower than the UPA2706GR-E2-AT's 15mΩ. This 47% reduction in RDS(on) significantly decreases conduction losses, leading to higher system efficiency, reduced heat generation, and improved thermal management. It enables more compact designs and enhances overall energy savings.
Furthermore, the VBA1311 supports a ±20V gate-source voltage, providing strong gate protection against ESD and noise, ensuring stable operation in electrically noisy environments. The 1.7V gate threshold voltage ensures easy drive compatibility with mainstream controller ICs, facilitating seamless integration without drive circuit adjustments.
Advanced Trench Technology for High Reliability and Switching Performance.
The UPA2706GR-E2-AT leverages advanced MOSFET technology for low loss. The VBA1311 utilizes VBsemi's mature Trench technology, which optimizes the cell structure to achieve an excellent balance between low on-resistance and switching characteristics. This technology ensures fast switching speeds, reduced switching losses, and high dv/dt capability, making it suitable for high-frequency applications like DC-DC converters and motor drives.
The device is subjected to rigorous quality control and 100% automated testing, ensuring high reliability and consistency. It operates over a wide temperature range and is designed to withstand demanding conditions, providing long-term stability for automotive, industrial, and consumer applications.
Fully Compatible SOP8 Package, Enabling Seamless Drop-In Replacement.
A primary concern in component substitution is the engineering effort required for integration. The VBA1311 addresses this by offering complete package compatibility. It uses a standard SOP8 package with identical pinout, pin spacing, and footprint as the UPA2706GR-E2-AT. Engineers can directly replace the component on the existing PCB without any layout changes, thermal redesign, or mechanical adjustments, achieving true "plug-and-play" substitution.
This high degree of compatibility drastically reduces the time and cost associated with validation and redesign. Sample verification can typically be completed within days, accelerating time-to-market. It also eliminates expenses related to PCB re-spins, tooling modifications, and requalification, making the transition to a domestic alternative smooth and economical.
Local Supply Chain Assurance and Responsive Technical Support.
Unlike imported components susceptible to logistics delays and geopolitical factors, VBsemi's VBA1311 benefits from a localized and stable supply chain within China's robust semiconductor ecosystem. With modern manufacturing and R&D facilities, VBsemi guarantees consistent production capacity and shorter lead times, typically within 2-3 weeks, with options for expedited delivery. This reliability mitigates risks associated with international trade tensions and supply disruptions.
As a local supplier, VBsemi provides dedicated, responsive technical support. Customers have access to comprehensive documentation, including detailed datasheets, application notes, and substitution guides. The technical team offers personalized assistance, capable of providing application-specific recommendations and troubleshooting support with rapid response times, often within 24 hours. This eliminates the communication barriers and slow support cycles often experienced with overseas suppliers.
From DC-DC power modules and motor drives to battery-powered devices and load switching circuits, the VBA1311, with its core strengths of "lower on-resistance, high efficiency, full package compatibility, stable supply, and local support," has become a preferred domestic alternative to the Renesas IDT UPA2706GR-E2-AT. It is already successfully deployed in various applications across multiple industries. Choosing the VBA1311 is not just a component swap; it is a strategic move towards supply chain security, cost optimization, and enhanced product performance—requiring no design risks while gaining superior efficiency, reliable availability, and immediate technical support.
