In various high-current, high-efficiency application scenarios such as power management systems, motor drives, battery protection circuits, DC-DC converters, and automotive electronics, RENESAS IDT's UPA2723T1A-E2-AZ, with its low on-resistance, high current handling, and compact design, has been a preferred component for engineers worldwide. However, in the face of global supply chain uncertainties, prolonged lead times, and rising procurement costs exacerbated by trade tensions, this imported part has revealed significant pain points: unpredictable availability (often extending to several months), price volatility due to currency fluctuations, and delayed technical support. These challenges increasingly hinder downstream manufacturers' production efficiency and cost management. Under these industry pressures, domestic substitution has evolved from an "alternative" to a "strategic imperative," offering a critical pathway for enterprises to secure supply chains, reduce expenses, and boost competitive edge.
Leveraging years of expertise in power semiconductor innovation, VBsemi introduces the VBQA1302 N-channel MOSFET, developed through independent R&D. This product is precisely tailored to replace the UPA2723T1A-E2-AZ, delivering core advantages of enhanced parameters, technological parity, and full package compatibility. It serves as a direct drop-in replacement without circuit modifications, providing a more reliable, cost-effective, and locally supported solution for high-current electronic systems.
Comprehensive Parameter Advancement, Robust Performance Margins, Adapting to Demanding Applications.
Designed as a domestic alternative to the UPA2723T1A-E2-AZ, the VBQA1302 achieves significant, leapfrog improvements in key electrical specifications, ensuring superior performance in high-current applications:
First, the continuous drain current is dramatically increased to 160A, vastly surpassing the original model's 33A—a nearly 385% enhancement in current-carrying capacity. This allows seamless adaptation to higher-power designs, whether upgrading existing systems or improving stability under heavy loads.
Second, the on-state resistance is as low as 1.8mΩ (@10V gate drive), outperforming the UPA2723T1A-E2-AZ's 3.5mΩ (@4.5V). This reduction significantly cuts conduction losses, directly boosting overall system efficiency. In high-frequency switching applications, it minimizes heat generation, easing thermal design constraints and lowering cooling costs.
Additionally, the VBQA1302 supports a ±20V gate-source voltage, offering enhanced gate ESD protection and noise immunity, preventing false triggering in noisy environments. The 1.7V gate threshold voltage balances drive simplicity and switching reliability, seamlessly matching mainstream driver ICs without circuit adjustments, further simplifying substitution.
Enhanced with Advanced Trench Technology, Reliability and Stability Elevated.
The UPA2723T1A-E2-AZ relies on its low RDS(on) and efficient switching characteristics. The VBQA1302 employs state-of-the-art Trench technology, building on these fundamentals while optimizing device reliability. It undergoes rigorous pre-screening and 100% testing, excelling in thermal and electrical stability. The optimized internal capacitance structure reduces switching losses and improves dv/dt tolerance, ensuring robust operation in high-frequency or transient conditions. With an operating temperature range of -55°C to 150°C, it withstands harsh industrial and automotive environments. Having passed extended reliability tests, including high-temperature/high-humidity aging, its failure rate is well below industry averages, providing dependable performance for critical applications like automotive systems, industrial controls, and power supplies.
Fully Compatible Package, Enabling "Seamless, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a key concern in domestic substitution is the cost and effort of redesign. The VBQA1302 addresses this through its package design. The device uses a DFN8(5X6) package, fully identical to the UPA2723T1A-E2-AZ in pinout, dimensions, and footprint. Engineers can replace it directly without PCB layout changes or thermal redesign, achieving true "plug-and-play" convenience. This compatibility slashes validation time—sample testing typically completes in 1-2 days—and avoids costs from PCB revisions or retooling. It also preserves original product certifications and外观, accelerating time-to-market and helping companies swiftly transition from imported components.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Technical Support.
Unlike imported parts prone to logistics delays, trade policies, and exchange rate risks, VBsemi capitalizes on China's mature semiconductor ecosystem, with modern production bases in Jiangsu and Guangdong. This enables full-control R&D and stable mass production of the VBQA1302. Standard lead times are compressed to under 2 weeks, with expedited orders allowing 72-hour delivery, mitigating risks from global supply chain disruptions. As a local brand, VBsemi offers dedicated technical support: comprehensive documentation includes substitution验证 reports, datasheets, thermal guides, and application circuits. The technical team provides "one-on-one" customization, with 24-hour response for troubleshooting, eliminating the slow support and high communication costs of imported components.
From power management and motor drives to battery protection and automotive electronics; from DC-DC converters and industrial equipment to consumer electronics, the VBQA1302—with its core strengths of "higher current, lower resistance, package compatibility, secured supply, and responsive service"—has become the premier domestic alternative to the UPA2723T1A-E2-AZ. It is already adopted by leading firms across sectors, earning strong market approval. Choosing the VBQA1302 is not just a component swap; it is a strategic move to enhance supply chain resilience, optimize costs, and improve product competitiveness—all without R&D risks, while gaining better performance, stable supply, and local support.
