In various low-voltage, small-signal application scenarios such as portable electronics, battery management systems, load switches, and power management modules, ROHM's UM6K1NTN, with its dual N-channel configuration and compact package, has been a popular choice for engineers worldwide. However, in the post-pandemic era with global supply chain disruptions and trade frictions, this imported component faces issues like unstable lead times, cost fluctuations due to exchange rates, and slow technical support responses. These challenges hinder production schedules and cost control for downstream companies. Therefore, domestic substitution has become a necessity for ensuring supply chain security and enhancing competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBK362K dual N-channel MOSFET based on independent R&D. This product directly对标es the UM6K1NTN, offering parameter upgrades, technological parity, and full package compatibility. It can serve as a drop-in replacement without circuit modifications, providing a stable, cost-effective, and locally supported solution for low-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance for Demanding Conditions.
Tailored as a domestic alternative to the UM6K1NTN, the VBK362K achieves significant improvements in key electrical parameters:
First, the drain-source voltage is increased to 60V, double the original model's 30V—a 100% improvement. This provides a wider safety margin in applications with voltage fluctuations, preventing overvoltage breakdown.
Second, the continuous drain current is raised to 0.3A (300mA), triple the original model's 100mA—a 200% enhancement in current-carrying capacity. This allows for higher load handling and improved system reliability.
Third, the on-state resistance is as low as 2500mΩ (@10V gate drive), significantly lower than the UM6K1NTN's 5Ω (@4V). This reduction in conduction loss improves efficiency and reduces heat generation, beneficial for compact designs.
Additionally, the VBK362K supports a ±20V gate-source voltage, offering robust ESD and noise immunity. The 1.7V gate threshold voltage ensures easy driving compatibility with mainstream ICs, simplifying the replacement process.
Advanced Trench Technology, Reliability and Stability Upgraded.
The UM6K1NTN relies on standard MOSFET technology. The VBK362K employs advanced Trench gate process, optimizing device reliability and switching performance. It undergoes rigorous testing, including high-voltage screening and environmental stress tests, ensuring high avalanche energy tolerance and stable operation under fast transients. The device features an operating temperature range of -55°C to 150°C, suitable for harsh conditions. With long-term reliability verification, its failure rate is below industry average, ideal for applications like medical devices, industrial control, and consumer electronics.
Fully Compatible Package, Enabling Seamless Replacement.
The VBK362K uses an SC70-6 package, identical to the UM6K1NTN in pinout, dimensions, and layout. Engineers can directly replace the component without PCB modifications or thermal redesign, achieving "plug-and-play" convenience. This compatibility reduces verification time to 1-2 days, avoids additional costs, and accelerates the substitution process.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Support.
Compared to imported components, VBsemi leverages China's semiconductor supply chain, with production bases in Jiangsu and Guangdong. The VBK362K has a standard lead time within 2 weeks, with expedited delivery options, mitigating risks from international logistics and tariffs. As a local brand, VBsemi provides dedicated technical support, including documentation, substitution reports, and circuit optimization. Technical issues are addressed within 24 hours, ensuring a smooth replacement experience.
From portable devices and battery packs to power management modules and low-voltage switches, the VBK362K, with its "superior parameters, stable performance, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the UM6K1NTN. It has been adopted by leading companies in various industries, gaining market recognition. Choosing the VBK362K is not just a component swap; it's a strategic move to enhance supply chain security, reduce costs, and boost product competitiveness—without R&D risks.
