In various low-voltage, high-efficiency application scenarios such as power management systems, motor drives, battery protection circuits, and portable devices, RENESAS's IDT UPA2792AGR-E1-AT, with its dual N-channel and P-channel MOSFET configuration, optimized on-resistance, and robust performance, has been a preferred choice for engineers worldwide. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component faces significant pain points: prolonged lead times (often extending to several months), procurement costs vulnerable to exchange rate swings, and delayed technical support. These challenges hinder production efficiency and cost control for downstream enterprises. Consequently, domestic substitution has evolved from an "option" to a "necessity," becoming a critical strategy for ensuring supply chain security, reducing costs, and enhancing competitiveness.
Leveraging years of expertise in power semiconductor design, VBsemi introduces the VBA5325 dual N-channel and P-channel MOSFET through independent R&D. This product is precisely tailored as a direct alternative to the UPA2792AGR-E1-AT, offering core advantages of parameter enhancements, technological parity, and full package compatibility. It enables seamless replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for various low-voltage electronic systems.
Comprehensive Parameter Enhancements, Ensuring Superior Performance and Adaptability.
Designed as a domestic drop-in replacement for the UPA2792AGR-E1-AT, the VBA5325 achieves notable improvements in key electrical parameters, providing robust performance for dual-channel applications:
Firstly, the drain-source voltage is rated at ±30V, matching the original model's 30V capability while offering symmetrical voltage tolerance for both N and P channels. This ensures reliable operation in circuits with bidirectional voltage swings, such as H-bridge motor drives and power switching systems.
Secondly, the continuous drain current is specified at ±8A per channel, which, while slightly lower than the original's 10A, remains ample for most low-voltage applications. This design balances current-carrying capacity with thermal efficiency, enabling stable performance in space-constrained designs like portable gadgets and compact power supplies.
Thirdly, the on-state resistance is significantly reduced to 18mΩ (@4.5V gate drive) for the N-channel and optimized for the P-channel, surpassing the UPA2792AGR-E1-AT's 26mΩ (@4.5V, 5A). This lower RDS(on) minimizes conduction losses, improving overall system efficiency and reducing heat generation—critical for high-frequency switching and energy-sensitive applications.
Additionally, the VBA5325 supports a ±20V gate-source voltage, enhancing gate ESD protection and noise immunity to prevent unintended turn-on in noisy environments. The gate threshold voltage of 1.6V to 1.7V ensures compatibility with mainstream driver ICs, simplifying drive circuit design and lowering substitution barriers.
Advanced Trench Technology, Delivering Enhanced Reliability and Switching Performance.
The UPA2792AGR-E1-AT relies on advanced MOSFET technology for low on-resistance and fast switching. The VBA5325 employs state-of-the-art Trench gate process, building upon the original model's strengths while optimizing device reliability. Through rigorous pre-screening, including 100% electrical testing and high-temperature validation, the device exhibits excellent avalanche energy handling and dv/dt tolerance. This makes it suitable for high-frequency switching and transient-heavy conditions, such as in DC-DC converters and motor control circuits. Moreover, the VBA5325 operates over a wide temperature range of -55°C to 150°C, enduring harsh industrial and outdoor environments. It has passed extended reliability tests, including high-temperature/high-humidity aging, ensuring a low failure rate for long-term operation—ideal for applications in automotive electronics, industrial automation, and consumer devices where durability is paramount.
Fully Compatible SOP8 Package, Enabling "Drop-In, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a major concern in domestic substitution is the R&D effort and time required for integration. The VBA5325 addresses this seamlessly through its package design. The device uses an SOP8 package, identical to the UPA2792AGR-E1-AT in pinout, pin spacing, and dimensions. Engineers can directly replace the original component on the PCB without layout changes or thermal redesign, achieving true "plug-and-play" substitution. This high compatibility reduces verification time to 1-2 days for samples, eliminates costs associated with PCB revisions or tooling adjustments, and preserves the original product's form factor and certifications. Consequently, it accelerates supply chain cycles, allowing enterprises to swiftly adopt domestic alternatives and capture market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to imported components plagued by logistic delays, trade policies, and currency fluctuations, VBsemi leverages China's robust semiconductor ecosystem, with modern production bases in Jiangsu and Guangdong ensuring full-process control and stable mass production of the VBA5325. Standard lead times are compressed to under 2 weeks, with emergency orders supporting 72-hour fast delivery. This mitigates risks from global supply chain volatility, tariffs, and geopolitics, safeguarding enterprise production schedules. As a local brand, VBsemi provides dedicated technical support through a "one-on-one" service model: offering comprehensive documentation—including substitution validation reports, datasheets, thermal guidelines, and application notes—alongside tailored selection advice and circuit optimization based on customer needs. Technical queries receive responses within 24 hours, with on-site or remote assistance available, resolving the slow support and high communication costs typical of imported components. This makes the substitution process smooth and worry-free.
From power management modules and motor drive circuits to battery protection systems and portable electronics, the VBA5325, with its core strengths of "enhanced parameters, reliable performance, package compatibility, controllable supply, and responsive service," has become the preferred domestic alternative to the UPA2792AGR-E1-AT. It is already adopted by leading firms across industries, earning high market recognition. Choosing the VBA5325 is not just a component swap; it is a strategic move for enterprises to upgrade supply chain resilience, optimize costs, and boost product competitiveness—all while avoiding R&D risks and gaining superior performance, stable supply, and accessible support.
