In high-power switching applications such as industrial motor drives, server & telecom power supplies, renewable energy inverters, and high-voltage DC-DC converters, the IXFH24N90P from Littelfuse IXYS has been a trusted choice for designers, known for its high voltage blocking capability and robust performance. However, reliance on imported components like this often brings challenges: extended lead times, vulnerability to international trade tensions, and higher costs influenced by currency fluctuations. These factors can disrupt production schedules and impact overall project viability. In this context, seeking a reliable domestic alternative has become a strategic imperative for ensuring supply chain resilience and cost efficiency.
Leveraging its advanced semiconductor technology and in-house R&D, VBsemi introduces the VBP19R20S N-channel power MOSFET. This device is designed as a direct, pin-to-pin replacement for the IXFH24N90P, offering not only full package compatibility but also superior electrical characteristics, providing a more efficient and dependable solution for demanding high-power circuits.
Key Parameter Advantages: Lower Losses, Higher Efficiency
While maintaining the same 900V drain-source voltage rating as the IXFH24N90P, the VBP19R20S delivers a significant performance upgrade in on-state resistance. Its RDS(on) is reduced to an impressive 205mΩ (at VGS=10V), which is less than half of the original part's 420mΩ. This dramatic reduction directly translates to lower conduction losses, enabling higher system efficiency, reduced heat generation, and potential for cooler operation or increased power density. The device supports a continuous drain current (ID) of 20A, making it suitable for a broad range of high-current applications. With a gate threshold voltage (Vth) of 3.5V and a wide gate-source voltage (VGS) range of ±30V, it ensures robust gate noise immunity and easy drive compatibility with standard controller ICs, requiring no circuit modifications.
Advanced Multi-EPI Super Junction Technology for Robust Performance
The VBP19R20S is built using VBsemi's proprietary SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology. This advanced process achieves an optimal balance between low on-resistance and fast switching performance. It offers excellent dv/dt capability and low gate charge, minimizing switching losses in high-frequency operation—a critical advantage in modern SMPS and inverter designs. The device is subjected to rigorous 100% avalanche energy testing and high-voltage screening, ensuring high reliability under voltage transients and surge conditions. With an extended operating temperature range and proven long-term reliability, it is engineered to perform reliably in harsh industrial environments, from motor control to solar inverters.
Seamless Drop-In Replacement with Full Package Compatibility
The VBP19R20S adopts the industry-standard TO-247 package, which is mechanically and electrically identical to the IXFH24N90P. This complete pin-to-pin and footprint compatibility allows for a true "drop-in" replacement. Engineers can substitute the component on existing PCB layouts without any redesign, saving significant development time, avoiding re-tooling costs, and accelerating time-to-market for product upgrades or localization projects.
Stable Supply and Local Technical Support
Produced within VBsemi's fully controlled manufacturing facilities, the VBP19R20S benefits from a stable and responsive domestic supply chain. Lead times are reliably short, eliminating the uncertainties associated with international logistics. Furthermore, VBsemi provides dedicated local technical support, offering comprehensive documentation, application guidance, and prompt assistance to ensure a smooth and successful design-in process for customers transitioning from the IXFH24N90P.
From industrial power systems and UPS units to high-voltage converters and welding equipment, the VBP19R20S stands out as a high-performance, reliable, and cost-effective domestic alternative to the IXFH24N90P. By choosing the VBP19R20S, designers not only secure their supply chain but also gain a component with superior efficiency and the backing of localized expert support—enabling enhanced end-product competitiveness without compromise.
