In various low-voltage, small-current application scenarios such as power switching, motor control, consumer electronics, battery management, and portable devices, MICROCHIP's VN10KN3-G-P002, with its stable performance and compact design, has been a common choice for engineers worldwide. However, in the post-pandemic era of global supply chain uncertainties and trade friction, this imported component faces growing pain points: extended lead times (often 2-4 months), procurement costs vulnerable to exchange rate swings, and delayed technical support. These issues hinder production schedules and cost efficiency for downstream companies. Given this demand, domestic substitution has evolved from an "option" to a "necessity," becoming a critical path for ensuring supply chain security, reducing costs, and enhancing competitiveness.
VBsemi, with deep expertise in power semiconductors, launches the VBR9N602K N-channel MOSFET based on independent R&D. This product precisely aligns with the VN10KN3-G-P002, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It serves as a direct drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for low-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance, Adapting to Diverse Conditions.
Tailored as a domestic alternative to the VN10KN3-G-P002, the VBR9N602K achieves significant improvements in key electrical parameters, providing robust performance for low-voltage applications:
Firstly, the drain-source voltage remains 60V, matching the original model, ensuring compatibility in standard low-voltage environments while offering reliable operation.
Secondly, the continuous drain current is increased to 0.45A (450mA), a 45% enhancement over the original model's 310mA. This higher current-carrying capability allows for handling more demanding loads, improving system stability and enabling design flexibility in upgraded or new applications.
Thirdly, the on-state resistance is reduced to 2000mΩ (2Ω) at 10V gate drive, significantly lower than the VN10KN3-G-P002's 5Ω. This 60% reduction in RDS(on) minimizes conduction losses, boosting overall efficiency and reducing heat generation, which simplifies thermal management in space-constrained designs.
Additionally, the VBR9N602K supports a ±20V gate-source voltage, offering strong gate ESD and noise immunity for reliable operation in noisy environments. The 0.8V gate threshold voltage ensures easy drive compatibility with mainstream ICs, avoiding drive circuit adjustments and lowering substitution barriers.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The VN10KN3-G-P002 relies on its design for low-current applications. The VBR9N602K employs advanced Trench technology, optimizing device performance and reliability. It features low on-resistance and fast switching characteristics, reducing switching losses and improving efficiency in high-frequency operations. The device undergoes rigorous pre-shipment testing, including avalanche and environmental stress tests, ensuring high reliability under transient conditions. With an operating temperature range of -55°C to 150°C, it adapts to harsh industrial and outdoor settings. Long-term reliability verifications, such as high-temperature aging tests, keep failure rates below industry averages, making it ideal for critical applications like automotive electronics, industrial controls, and medical devices.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, substitution costs and efforts are key concerns. The VBR9N602K addresses this through package design. It uses a TO-92 package, fully compatible with the VN10KN3-G-P002 in pinout, spacing, dimensions, and mounting. Engineers need not alter PCB layouts or thermal designs, achieving seamless "plug-and-play" replacement. This compatibility slashes verification time—sample validation typically completes in 1-2 days—and avoids PCB redesign costs and re-certification hurdles. It streamlines supply chains, enabling quick import substitution and market responsiveness.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to import-related risks like logistics delays and geopolitical factors, VBsemi leverages China's mature semiconductor ecosystem, with production bases in Jiangsu and Guangdong ensuring full-process control and stable mass production. The VBR9N602K boasts a standard lead time under 2 weeks, with emergency orders supporting 72-hour delivery, mitigating supply chain volatility and tariff impacts.
