In various medium-voltage application scenarios such as DC-DC converters, motor control, power management systems, and automotive electronics, Texas Instruments' IRFU110, with its balanced performance and robust design, has been a common choice for engineers globally during component selection. However, in the context of global supply chain uncertainties and trade volatility, this imported part has increasingly revealed pain points: extended lead times, cost sensitivity to currency fluctuations, and delayed technical support. These challenges hinder production efficiency and cost control for downstream companies. As a result, domestic substitution has evolved from an "alternative" to a "necessity," becoming a critical strategy for ensuring supply chain resilience, reducing expenses, and enhancing competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi has introduced the VBFB1102M N-channel power MOSFET through independent R&D. This product is meticulously designed to match the IRFU110, offering core advantages of parameter enhancements, technological parity, and full package compatibility. It serves as a drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for medium-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance, Adapting to Demanding Conditions.
Tailored as a domestic alternative to the IRFU110, the VBFB1102M achieves significant improvements in key electrical parameters, providing superior performance for medium-voltage applications:
Firstly, the drain-source voltage is maintained at 100V, matching the original model's rating, ensuring compatibility in standard voltage environments while offering reliable operation.
Secondly, the continuous drain current is dramatically increased to 12A, surpassing the original model's 4.7A by over 155%. This substantial enhancement in current-carrying capacity allows for handling higher power loads with ease, enabling upgrades to higher-power designs or improving system stability at existing power levels.
Thirdly, the on-state resistance is reduced to 200mΩ (@10V gate drive), significantly lower than the IRFU110's 540mΩ. This reduction minimizes conduction losses, boosting overall efficiency and reducing heat generation, which alleviates thermal management demands and lowers energy costs in high-frequency switching applications.
Additionally, the VBFB1102M supports a ±20V gate-source voltage, providing strong gate ESD protection and noise immunity to prevent unintended turn-on in noisy environments. The 1.5V gate threshold voltage ensures easy drive compatibility with mainstream driver ICs, eliminating the need for drive circuit adjustments and simplifying the substitution process.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The IRFU110 is known for its reliable performance in medium-voltage circuits. The VBFB1102M employs advanced Trench technology, which optimizes switching characteristics and enhances device reliability. Through rigorous testing, including avalanche energy validation and high-voltage screening, the device demonstrates robust single-pulse avalanche capability, effectively managing energy surges during turn-off to reduce breakdown risks. The optimized intrinsic capacitance design not only lowers switching losses but also improves dv/dt tolerance, ensuring stable operation in high-frequency and transient conditions. Moreover, the VBFB1102M features an extended operating temperature range and has passed long-term reliability tests such as high-temperature/high-humidity aging, resulting in a failure rate well below industry averages. This makes it ideal for applications requiring high reliability, including automotive systems, industrial controls, and power supplies.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream companies, a key concern in domestic substitution is the cost and effort involved in redesign. The VBFB1102M addresses this seamlessly through its package design. The device uses a TO-251 package, which is fully compatible with the IRFU110's TO-251 package in pinout, pin spacing, dimensions, and heatsink interface. Engineers can directly replace the component without modifying PCB layouts or thermal designs, achieving a hassle-free "plug-and-play" substitution. This high compatibility reduces verification time—sample validation can typically be completed within 1-2 days—and avoids additional costs from PCB revisions or retooling. It also preserves original product certifications and外观, accelerating the supply chain transition and helping companies quickly adopt domestic alternatives.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
