In various low-voltage, compact application scenarios such as switching circuits, portable devices, and space-constrained electronic systems, ROHM's UM6J1NTN, with its dual P-channel MOSFETs in a single UMT package, independent transistor elements eliminating mutual interference, and the ability to halve installation cost and area, has been a significant choice for engineers worldwide during design selection. However, against the backdrop of global supply chain disruptions and trade uncertainties, this imported component faces pain points like unstable lead times, procurement costs susceptible to fluctuations, and lagging technical support responses, severely constraining downstream companies' production schedules and cost control. Given this industry demand, domestic substitution has transitioned from an "option" to a "necessity," becoming a critical path for enterprises to ensure supply chain security, reduce costs, and enhance competitiveness.
VBsemi, with deep expertise in power semiconductor technology, has launched the VBK4223N dual P-channel MOSFET based on independent R&D. This product precisely targets the UM6J1NTN, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It can serve as a direct replacement without any modifications to the original circuit, providing a more stable, cost-effective, and locally attuned high-quality solution for various low-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance for Demanding Conditions.
Tailored as a domestic alternative to the UM6J1NTN, the VBK4223N achieves significant, leapfrog improvements in key electrical parameters, offering more robust performance guarantees:
Firstly, the drain-source voltage is specified at -20V, ensuring reliable operation in typical low-voltage circuits, while the UM6J1NTN supports 30V. This optimized rating provides sufficient margin for applications like battery-powered devices and low-power switches.
Secondly, the continuous drain current is increased to -1.8A, a substantial enhancement over the original model's 200mA—representing a 900% improvement in current-carrying capability. This enables effortless adaptation to higher load demands, improving system stability and power handling.
Thirdly, the on-state resistance is as low as 235mΩ at gate drives of 2.5V and 4.5V, significantly lower than the UM6J1NTN's 1.4Ω at 10V. This reduction minimizes conduction losses, enhances efficiency, and reduces heat generation, crucial for compact designs and energy-sensitive applications.
Additionally, the VBK4223N supports a ±12V gate-source voltage, offering stronger gate ESD and noise immunity, preventing unintended turn-on in noisy environments. The -0.6V gate threshold voltage balances driving convenience and switching reliability, seamlessly matching mainstream driver ICs without requiring drive circuit adjustments, further lowering the substitution barrier.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the UM6J1NTN lies in its dual independent MOSFETs in a UMT package, eliminating interference. The VBK4223N employs advanced Trench technology, building upon the original's isolation benefits while optimizing device performance and reliability. It features low on-resistance and fast switching characteristics, ideal for high-frequency switching applications. The device undergoes rigorous testing, including high-temperature and high-humidity aging tests, ensuring long-term durability in harsh conditions. With an operating temperature range of -55°C to 150°C, it adapts to diverse environments such as industrial controls, automotive electronics, and portable gadgets. Its robust design reduces failure rates, providing solid assurance for continuous operation in critical fields like medical devices and communication systems.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a core concern regarding domestic substitution is the R&D investment and time costs involved. The VBK4223N fundamentally addresses this through its package design. The device uses an SC70-6 package, which is fully compatible with the UM6J1NTN's UMT package in pinout, dimensions, and footprint. Engineers need not modify the original PCB layout or thermal design, achieving "plug-and-play" replacement. This compatibility slashes verification time to 1-2 days, eliminates costs from PCB revisions, and preserves product aesthetics and certifications. It effectively shortens the supply chain cycle, helping enterprises quickly adopt domestic alternatives and seize market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to the unstable supply chain of imported components, VBsemi leverages China's robust semiconductor industry chain, with modern production bases in Jiangsu and Guangdong, enabling full-process R&D and stable mass production of the VBK4223N. Lead times are compressed to within 2 weeks, with emergency orders enabling 72-hour rapid delivery, mitigating risks from international volatility and trade barriers. As a local brand, VBsemi offers professional technical support with "one-on-one" services: comprehensive documentation including substitution verification reports, datasheets, and application guides, plus tailored solutions based on customer scenarios. Technical issues receive rapid response within 24 hours, via on-site or remote assistance,彻底 resolving slow support and high communication costs associated with imports, making substitution smoother and worry-free.
From switching circuits and portable electronics to industrial controls and automotive systems, the VBK4223N, with its core advantages of "superior parameters, enhanced performance, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the UM6J1NTN. It has already achieved adoption in leading companies across industries, receiving high market recognition. Choosing the VBK4223N is not merely a component replacement; it is a strategic step for enterprises to upgrade supply chain security, optimize costs, and boost competitiveness—requiring no R&D modification risks while enjoying better performance, stable supply, and convenient support.
