In high-voltage, high-frequency application scenarios such as switch-mode power supplies, industrial inverters, LED lighting drivers, and motor control systems, RENESAS's 2SK3116-S-AZ N-channel power MOSFET has been a trusted component for engineers worldwide, known for its balanced performance and robustness. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported part reveals growing pain points: extended lead times (often spanning months), costs vulnerable to currency fluctuations, and delayed technical support. These challenges increasingly hinder downstream manufacturers' production efficiency and cost management. Against this backdrop, domestic substitution has evolved from an alternative to a necessity, becoming a critical strategy for ensuring supply chain resilience, reducing expenses, and enhancing core competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBN165R07 N-channel power MOSFET, developed through independent R&D as a precise domestic alternative to the 2SK3116-S-AZ. With core strengths in parameter enhancements, technological parity, and full package compatibility, it enables direct drop-in replacement without circuit modifications, offering a more stable, cost-effective, and locally supported solution for diverse high-voltage electronic systems.
Comprehensive Parameter Optimization, Enhanced Performance Margins for Demanding Conditions.
Tailored to replace the 2SK3116-S-AZ, the VBN165R07 delivers key electrical parameter improvements, providing robust performance guarantees in high-voltage applications:
First, the drain-source voltage is elevated to 650V, surpassing the original model's 600V by 50V—an 8.3% increase. This upgrade offers a greater safety margin in environments with grid fluctuations or transient overvoltage risks, effectively preventing device failure due to overvoltage breakdown.
Second, the continuous drain current is rated at 7A, ensuring reliable current-handling capacity for most high-power designs. While slightly below the original 7.5A, this is compensated by superior thermal management and efficiency, maintaining stability in applications such as power supplies and motor drives.
Third, the on-state resistance is 1300mΩ (@10V gate drive), providing competitive conduction loss performance. Coupled with advanced planar technology, it contributes to reduced heat generation and improved system efficiency, particularly in high-frequency switching scenarios.
Additionally, the VBN165R07 supports a ±30V gate-source voltage, enhancing gate ESD protection and noise immunity to prevent unintended turn-on in complex electromagnetic environments. The 3.5V gate threshold voltage ensures compatibility with mainstream driver ICs, simplifying drive circuit design and lowering substitution barriers.
Advanced Planar Gate Technology, Reliability and Stability Inherited and Upgraded.
The 2SK3116-S-AZ relies on proven design for reliability, but the VBN165R07 employs industry-leading Planar gate process technology, optimizing device robustness across multiple dimensions. Each device undergoes 100% avalanche testing and high-voltage screening, demonstrating excellent single-pulse avalanche energy tolerance to handle energy surges during high-voltage switching. Through optimized intrinsic capacitance design, it reduces switching charge/discharge losses and enhances dv/dt tolerance, matching the 2SK3116-S-AZ's application scenarios seamlessly. Even under harsh conditions like high-frequency operation or fast transients, it maintains stable performance without circuit topology changes. Furthermore, the VBN165R07 operates across an ultra-wide temperature range of -55°C to 150°C, adapting to industrial high-temperature or extreme climate environments. It has passed rigorous 1000-hour high-temperature/high-humidity (85°C/85% RH) aging tests and long-term reliability verification, with a failure rate well below industry averages, ensuring durable operation in critical fields like industrial control, emergency power, and LED lighting.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement with Zero Risk.
A major concern in domestic substitution is the R&D effort and time cost. The VBN165R07 addresses this directly through its package design. It utilizes a TO-262 package, which is fully compatible with the 2SK3116-S-AZ in pinout, pin spacing, dimensions, and heatsink interface. Engineers can replace the original component without modifying PCB layouts or thermal designs, achieving true "plug-and-play" convenience. This high compatibility slashes verification time—sample validation typically completes in 1-2 days—and avoids extra costs from PCB revisions or mold adjustments. It also preserves original product structures, eliminating re-certification needs, thus shortening supply cycles and helping enterprises swiftly upgrade imported components to capture market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Technical Support.
Unlike imported parts affected by international logistics, trade policies, or exchange rates, VBsemi leverages China's integrated semiconductor industry chain, with modern production bases and R&D centers in Jiangsu and Guangdong, enabling full-process control and stable mass production of the VBN165R07. Standard lead times are compressed to under 2 weeks, with emergency orders supporting 72-hour fast delivery, mitigating risks from supply chain volatility, tariffs, or geopolitics. As a local brand, VBsemi provides dedicated technical support with "one-on-one" customized services: comprehensive documentation including substitution验证 reports, datasheets, thermal guides, and application circuits, plus tailored selection advice and circuit optimization based on customer scenarios. For any substitution issues, the technical team responds within 24 hours for on-site or remote resolution, eliminating slow support and high communication costs associated with imported components, making substitution smooth and worry-free.
From industrial switch-mode power supplies and high-frequency inverters to LED drivers, welding machines, UPS systems, and motor control, the VBN165R07, with its core advantages of "superior voltage rating, reliable performance, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the 2SK3116-S-AZ. It is already adopted by leading companies across industries, earning strong market recognition. Choosing the VBN165R07 is not just a component swap—it's a strategic move to upgrade supply chain security, optimize costs, and boost product competitiveness, requiring no R&D modification risks while benefiting from enhanced performance, stable supply, and responsive support.
