In low-voltage, high-current application scenarios such as power management modules, motor drives, battery protection circuits, and load switch systems, Renesas' UPA2717AGR-E1-AT, with its P-channel configuration, low on-resistance, and compact SOP8 package, has been a reliable choice for designers seeking efficient power switching solutions. However, amidst global semiconductor supply uncertainties and extended lead times for specific imported components, reliance on such parts can pose risks to production continuity and cost predictability. This situation has accelerated the shift toward domestic alternatives, transforming them from a backup plan into a strategic necessity for securing supply chains and enhancing design flexibility.
Leveraging its expertise in power semiconductor development, VBsemi introduces the VBA2305 P-channel MOSFET as a precise, high-performance domestic substitute for the UPA2717AGR-E1-AT. Designed with parameter enhancements, technological robustness, and full package compatibility, the VBA2305 enables direct replacement without circuit modifications, delivering a more accessible, stable, and cost-effective solution for modern low-voltage power applications.
Superior Electrical Parameters for Enhanced Performance and Reliability
As a targeted alternative to the UPA2717AGR-E1-AT, the VBA2305 demonstrates meaningful improvements across key specifications, providing stronger performance margins and greater design headroom:
The continuous drain current (Id) is rated at -18A, outperforming the original’s 15A—a 20% increase in current-handling capability. This allows the VBA2305 to support higher load currents with ease, improving system robustness in demanding applications.
The on-resistance is specified at 5mΩ (at Vgs=10V), lower than the UPA2717AGR-E1-AT’s 5.5mΩ. This reduction directly minimizes conduction losses, enhances power efficiency, and reduces thermal dissipation—particularly beneficial in space-constrained or thermally sensitive designs.
The device supports a gate-source voltage (Vgs) of ±20V, offering strong gate noise immunity and ESD protection in electrically noisy environments. With a gate threshold voltage (Vth) of -3V, it remains compatible with common low-voltage drive circuits, ensuring easy integration without driver re-design.
Advanced Trench Technology for Low Loss and High Durability
The UPA2717AGR-E1-AT relies on Renesas' optimized P-channel process for low RDS(on) and efficient switching. The VBA2305 employs VBsemi’s mature Trench technology, which further reduces on-resistance and improves switching characteristics. Through careful optimization of the cell structure and gate charge, the device achieves lower switching losses and better thermal performance, supporting high-frequency operation where efficiency is critical. It undergoes rigorous reliability testing, including high-temperature and high-humidity stress tests, ensuring stable operation across an industrial temperature range and extended product lifespan—making it suitable for automotive, industrial, and consumer applications where durability is essential.
Full SOP8 Package Compatibility for Seamless Replacement
A major concern during component substitution is the redesign effort and validation time required. The VBA2305 eliminates these hurdles through full mechanical and footprint compatibility. It is offered in the industry-standard SOP8 package, matching the UPA2717AGR-E1-AT in pinout, dimensions, and mounting footprint. Engineers can replace the original component directly on the existing PCB layout without modifying circuitry, thermal design, or mechanical enclosures. This plug-and-play compatibility dramatically shortens validation cycles—often completed within days—and avoids costs associated with re-layout, re-tooling, or re-certification, enabling fast and risk-free adoption.
Local Supply Chain Agility and Responsive Technical Support
Unlike imported alternatives subject to logistics delays, allocation shortages, or currency fluctuations, VBsemi’s domestic manufacturing base ensures stable production and shorter lead times for the VBA2305. Standard delivery is typically within weeks, with expedited options available for urgent needs. This supply stability helps companies mitigate external uncertainties and maintain production schedules. Moreover, VBsemi provides direct, responsive technical support, including detailed substitution guides, datasheets, application notes, and circuit recommendations. Designers can access timely assistance for integration challenges, ensuring a smooth and confident transition.
From DC-DC converters and battery-powered systems to motor control and smart load switching, the VBA2305 stands out as a superior domestic alternative to the UPA2717AGR-E1-AT. With better electrical characteristics, proven reliability, seamless package compatibility, and dependable local supply, it enables companies to reduce dependency on imported components while improving performance and supply chain control. Adopting the VBA2305 is more than a component swap—it is a strategic upgrade toward greater design autonomy, cost efficiency, and long-term supply security.
