In various high-current, high-power application scenarios such as industrial motor drives, switch-mode power supplies, welding equipment, UPS systems, and electric vehicle charging, Littelfuse IXYS's IXTH24N50, with its robust N-channel design, high voltage tolerance, and efficient switching capabilities, has long been a key component for engineers worldwide. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported MOSFET has revealed significant pain points: extended lead times (often exceeding 3-4 months), costs vulnerable to currency fluctuations, and delayed technical support. These challenges hinder production schedules and cost optimization for downstream enterprises, making domestic substitution not just an option but a necessity to ensure supply chain resilience, reduce expenses, and boost competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBP15R50S N-channel power MOSFET through independent R&D. This product is meticulously designed to对标 the IXTH24N50, offering core advantages of parameter enhancement, 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 high-current electronic systems.
Comprehensive Parameter Surpassing, Superior Performance for Demanding Conditions.
Tailored as a domestic alternative to the IXTH24N50, the VBP15R50S achieves leapfrog improvements in critical electrical parameters, ensuring robust performance in high-power applications:
First, the drain-source voltage remains at 500V, matching the original model, while providing a reliable foundation for high-voltage environments with transient overvoltage risks.
Second, the continuous drain current is dramatically increased to 50A, more than doubling the original model's 24A—a 108% enhancement in current-carrying capacity. This allows seamless adaptation to higher power designs, whether upgrading existing systems or improving stability at similar power levels.
Third, the on-state resistance is reduced to just 80mΩ (@10V gate drive), significantly lower than the IXTH24N50's 230mΩ. This 65% reduction in RDS(on) minimizes conduction losses, boosting overall efficiency and reducing heat generation. In high-frequency switching applications, it alleviates thermal management pressure and cuts energy costs.
Additionally, the VBP15R50S supports a ±30V gate-source voltage, offering enhanced gate ESD and noise immunity to prevent unintended turn-on in noisy environments. The 3.8V gate threshold voltage balances drive convenience and switching reliability, compatible with mainstream driver ICs without circuit adjustments, simplifying substitution.
Enhanced with Advanced SJ_Multi-EPI Technology, Reliability and Efficiency Upgraded.
The IXTH24N50 relies on proven MOSFET technology for performance, but the VBP15R50S employs state-of-the-art SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology. This innovation builds on low on-resistance and fast switching, while optimizing device reliability. The VBP15R50S undergoes rigorous avalanche testing and high-voltage screening, excelling in single-pulse avalanche energy handling to withstand surges during turn-off, reducing failure risks. Through optimized capacitance design, it lowers switching losses and enhances dv/dt tolerance, matching the IXTH24N50's application scenarios. Even under harsh conditions like high-frequency operation and rapid transients, it maintains stable performance. Moreover, it features an operating temperature range of -55°C to 150°C, suitable for industrial high-temperature and extreme climates. Having passed 1000-hour high-temperature/high-humidity (85°C/85% RH) aging tests and long-term reliability verification, its failure rate is below industry averages, ensuring durability for critical applications like industrial automation, renewable energy, and medical devices.
Fully Compatible Package, Enabling Seamless and Risk-Free Replacement.
For downstream companies, domestic substitution often concerns R&D effort and time costs. The VBP15R50S addresses this through its package design. It uses a TO-247 package, identical to the IXTH24N50 in pinout, pin spacing, dimensions, and heatsink compatibility. Engineers can perform a plug-and-play replacement without altering PCB layouts or thermal designs. This high compatibility slashes verification time—sample validation typically completes in 1-2 days—and avoids costs from PCB revisions or retooling. It also preserves original product certifications and外观, accelerating supply chain cycles and helping enterprises swiftly replace imported components to capture market opportunities.
