In various medium-high voltage application scenarios such as power supplies, motor drives, and industrial controls, RENESAS' RJK5026DPP-00#T2, with its balanced performance and compact design, has been a common choice for engineers during component selection. However, in the face of global supply chain uncertainties and procurement challenges, this imported part often presents issues like extended lead times, cost volatility, and limited technical support, which hinder production efficiency and cost management for downstream enterprises. In this context, domestic substitution has evolved from an alternative to a necessity, becoming a key strategy for ensuring supply chain security and enhancing competitiveness.
Leveraging its expertise in power semiconductors, VBsemi introduces the VBMB155R09 N-channel power MOSFET through independent R&D. This product is precisely tailored as a direct alternative to the RJK5026DPP-00#T2, offering advantages in parameter upgrades, technological parity, and full package compatibility. It enables a drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for various electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance for Demanding Conditions.
Designed as a domestic substitute for the RJK5026DPP-00#T2, the VBMB155R09 achieves significant improvements in key electrical parameters, providing robust performance guarantees:
First, the drain-source voltage is increased to 550V, 50V higher than the original model's 500V—a 10% enhancement. This offers a greater safety margin in environments with voltage fluctuations or transient overvoltages, reducing the risk of device breakdown.
Second, the continuous drain current is raised to 9A, substantially surpassing the original model's 6A—a 50% increase in current-carrying capacity. This allows for handling higher power levels and improves system stability in existing designs.
Third, the on-state resistance is as low as 1000mΩ (@10V gate drive), outperforming the RJK5026DPP-00#T2's 1.7Ω (1700mΩ). This reduction minimizes conduction losses, enhancing overall efficiency and reducing heat generation in high-frequency switching applications.
Additionally, the VBMB155R09 supports a ±30V gate-source voltage, providing stronger gate ESD protection and noise immunity. The 3.2V gate threshold voltage ensures compatibility with mainstream driver ICs, simplifying drive circuit design and lowering substitution barriers.
Advanced Planar Technology, Reliability and Stability Upgraded.
While the RJK5026DPP-00#T2 relies on its optimized design for performance, the VBMB155R09 employs advanced Planar gate technology to enhance reliability. The device undergoes rigorous avalanche testing and high-voltage screening, ensuring excellent avalanche energy handling and durability against voltage surges. Through optimized capacitance design, it reduces switching losses and improves dv/dt tolerance, matching the application scenarios of the original model. With an operating temperature range of -55°C to 150°C and validation through high-temperature/high-humidity aging tests, it offers long-term reliability suitable for industrial, automotive, and critical infrastructure applications.
Fully Compatible Package, Enabling Seamless Replacement.
The VBMB155R09 addresses substitution concerns through package compatibility. It uses a TO-220F package identical to the RJK5026DPP-00#T2 in pinout, dimensions, and heatsink structure. Engineers can replace the component directly without PCB layout changes or thermal redesign, achieving "plug-and-play" convenience. This compatibility reduces verification time to 1-2 days, avoids additional costs from modifications, and accelerates supply chain integration.
Local Strength Assurance, Dual Peace of Mind for Supply and Support.
Compared to imported components with unstable supply chains, VBsemi leverages domestic manufacturing bases in Jiangsu and Guangdong to ensure stable mass production of the VBMB155R09. Lead times are compressed to within 2 weeks, with emergency delivery options, mitigating risks from international logistics and trade policies. As a local brand, VBsemi provides dedicated technical support, including comprehensive documentation, substitution reports, and circuit optimization advice. Technical issues receive responses within 24 hours, eliminating slow support and communication barriers associated with imported parts.
From power supplies and motor drives to industrial controls and automotive systems, the VBMB155R09, with its core advantages of "superior parameters, enhanced reliability, package compatibility, controllable supply, and responsive service," has become the preferred domestic alternative to the RJK5026DPP-00#T2. It has gained market recognition in various industries, offering enterprises a strategic step toward supply chain security, cost optimization, and product competitiveness—without R&D risks but with better performance, stable supply, and local support.
