In various medium-voltage application scenarios such as switch-mode power supplies, motor drives, industrial inverters, and UPS systems, RENESAS's 2SK2729-E N-channel power MOSFET has been a reliable choice for engineers due to its balanced performance. However, amid global supply chain disruptions and trade uncertainties in the post-pandemic era, this imported component faces challenges like extended lead times (often months), cost volatility from exchange rates, and delayed technical support, hindering production efficiency and cost control. Consequently, domestic substitution has evolved from an option to a necessity, crucial for securing supply chains, reducing costs, and boosting competitiveness.
VBsemi, leveraging its expertise in power semiconductors, introduces the VBPB15R18S N-channel power MOSFET as a direct alternative to the 2SK2729-E. This product offers parameter upgrades, technological equivalence, and full package compatibility, enabling a drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for medium-voltage electronic systems.
Comprehensive Parameter Advancements, Ensuring Performance Redundancy for Demanding Conditions.
Tailored as a domestic alternative to the 2SK2729-E, the VBPB15R18S achieves key electrical parameter improvements, providing robust performance for 500V applications. First, the drain-source voltage remains at 500V, matching the original model for consistent medium-voltage operation. Second, the continuous drain current is 18A, slightly lower than the original 20A but still sufficient for most designs, with enhanced efficiency. Third, the on-state resistance is reduced to 210mΩ (@10V gate drive), a 27.6% improvement over the 2SK2729-E's 290mΩ, significantly lowering conduction losses and improving overall system efficiency. Additionally, the VBPB15R18S supports a ±30V gate-source voltage, offering strong gate ESD and noise immunity, while the 3.5V gate threshold voltage ensures compatibility with mainstream driver ICs, simplifying drive circuit design.
Enhanced with Advanced SJ_Multi-EPI Technology, Reliability and Stability Upgraded.
The VBPB15R18S utilizes SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology, delivering low on-resistance and excellent switching characteristics comparable to the original model. This technology enhances device reliability through optimized avalanche energy capability and high dv/dt tolerance. The device undergoes 100% avalanche testing and high-voltage screening, ensuring robust performance in high-frequency switching and transient conditions. With an operating temperature range of -55°C to 150°C and passing long-term reliability tests like 1000-hour high-temperature/high-humidity aging, the VBPB15R18S offers superior stability for critical applications such as industrial controls, medical equipment, and emergency power systems.
Fully Compatible Package, Enabling Seamless and Risk-Free Replacement.
The VBPB15R18S features a TO3P package, fully compatible with the 2SK2729-E in pinout, dimensions, and heatsink structure. Engineers can directly replace the original component without PCB layout changes or thermal adjustments, achieving plug-and-play substitution. This compatibility reduces verification time to 1-2 days, eliminates redesign costs, and avoids recertification, accelerating the substitution process.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Technical Support.
Benefiting from China's mature semiconductor industry chain, VBsemi ensures stable mass production of the VBPB15R18S with lead times within 2 weeks and expedited 72-hour delivery options, mitigating risks from international supply volatility and trade barriers. As a local brand, VBsemi provides dedicated technical support, including comprehensive documentation, substitution verification reports, and rapid 24-hour response for issues, addressing the slow support and high communication costs of imported components.
From switch-mode power supplies and motor drives to industrial inverters and UPS systems, the VBPB15R18S, with its advantages of lower on-resistance, enhanced efficiency, package compatibility, controllable supply, and responsive support, has become the preferred domestic alternative to the 2SK2729-E. It has been successfully adopted by leading companies across industries. Choosing the VBPB15R18S is not just a component replacement but a strategic step to upgrade supply chain security, optimize costs, and enhance competitiveness—without R&D risks, while enjoying better performance, stable supply, and convenient support.
