In medium-voltage, high-current application fields such as motor drives, power tools, DC-DC converters, and battery management systems, Littelfuse IXYS's IXTA64N10L2-TRL, known for its low on-resistance and robust current-handling capability, has been a popular choice for design engineers. However, facing challenges like extended lead times, cost volatility due to global trade dynamics, and slower remote technical support, the need for a reliable, locally sourced alternative has become urgent for ensuring supply chain resilience and cost efficiency. Responding to this market demand, VBsemi introduces the VBL1104N N-channel power MOSFET, a purpose-built domestic substitute for the IXTA64N10L2-TRL, delivering parameter enhancements, full package compatibility, and stable local supply without requiring circuit redesign.
Superior Electrical Parameters for Enhanced Performance and Efficiency
Developed as a direct alternative to the IXTA64N10L2-TRL, the VBL1104N offers key electrical improvements that provide greater design margin and operational reliability:
- Voltage & Current Ratings: With a drain-source voltage (VDS) of 100V, it matches the original part's voltage rating, ensuring suitability for the same application environments. The continuous drain current (ID) is rated at 45A, offering substantial current capacity for a wide range of medium-power applications.
- Lower On-Resistance: The VBL1104N features a remarkably low on-resistance (RDS(on)) of 30mΩ at 10V gate drive, outperforming the 32mΩ of the IXTA64N10L2-TRL. This reduction in conduction loss translates directly into higher system efficiency, reduced heat generation, and potential savings in thermal management design.
- Gate Characteristics: The device supports a gate-source voltage (VGS) of ±20V, providing strong noise immunity and protection against gate stress. A gate threshold voltage (Vth) of 1.8V ensures easy drive compatibility with common controller ICs, facilitating seamless integration.
Advanced Trench Technology for Robust Switching and Reliability
While the IXTA64N10L2-TRL relies on mature trench technology for low RDS(on), the VBL1104N utilizes VBsemi's optimized Trench process to achieve an excellent balance of low conduction loss and reliable switching performance. The structure is designed to minimize gate charge and output capacitance, reducing switching losses in high-frequency operation. The device undergoes rigorous reliability testing, including high-temperature operating life (HTOL) and repetitive avalanche testing, ensuring stable performance under demanding conditions such as inductive load switching and transient surges. With an operational temperature range extending from -55°C to 175°C, it is well-suited for industrial, automotive, and outdoor applications where temperature fluctuations are common.
Drop-In Package Compatibility for Quick and Risk-Free Replacement
The VBL1104N is offered in a TO-263 package, which is fully compatible in footprint, pinout, and mounting dimensions with the IXTA64N10L2-TRL's TO-263 variant. This complete mechanical and electrical compatibility allows engineers to replace the incumbent part without modifying PCB layout, heatsink design, or assembly process. The "plug-and-play" substitution significantly shortens verification time, eliminates redesign cost, and accelerates time-to-market for end products.
Local Supply Chain Assurance and Responsive Technical Support
Unlike imported alternatives subject to logistics delays and currency risks, VBsemi manufactures the VBL1104N within its domestic production facilities, ensuring shorter lead times (typically within 2–3 weeks) and consistent supply. The company provides comprehensive technical documentation, including substitution guides, application notes, and SPICE models, along with direct engineer-to-engineer support for design-in assistance and troubleshooting. This local presence eliminates communication barriers and ensures prompt response, reducing dependency on overseas suppliers.
From motor controllers and uninterruptible power supplies to industrial inverters and portable power systems, the VBL1104N stands as a high-performance, reliable, and cost-effective domestic alternative to the IXTA64N10L2-TRL. Its advantages in lower RDS(on), package compatibility, and secured supply chain make it an ideal choice for companies aiming to improve supply stability, reduce costs, and enhance product competitiveness without incurring redesign risks or performance compromises.
