In high-voltage application scenarios such as DC-DC converters and battery chargers, Littelfuse IXYS's IXFH18N100Q3, with its low intrinsic gate resistance, standard international packaging, low package inductance, fast intrinsic rectifier, low on-resistance and gate charge, and high power density, has been a key choice for engineers in design selection. However, in the post-pandemic era of global supply chain disruptions and trade frictions, this imported component faces pain points like unstable lead times, cost volatility due to exchange rates, and slow technical support, constraining production schedules and cost control for downstream companies. Given this demand, domestic substitution has shifted from an "option" to a "necessity," becoming critical for ensuring supply chain security, reducing costs, and enhancing competitiveness.
VBsemi, leveraging years of expertise in power semiconductors, introduces the VBP110MR24 N-channel power MOSFET based on independent R&D. This product precisely对标es the IXFH18N100Q3, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It serves as a direct replacement without circuit modifications, providing a more stable, cost-effective, and locally attuned solution for high-voltage electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the IXFH18N100Q3, the VBP110MR24 achieves leapfrog improvements in key electrical parameters, ensuring robust performance for high-voltage applications:
Firstly, the drain-source voltage maintains 1000V, matching the original model's rating, ensuring reliability in applications with high voltage demands such as industrial power systems and renewable energy infrastructure.
Secondly, the continuous drain current is significantly increased to 24A, offering superior current-carrying capability compared to the original model. This enhancement allows effortless adaptation to higher power designs, whether upgrading equipment or improving system stability at similar power levels.
Thirdly, the on-state resistance is dramatically reduced to 420mΩ (@10V gate drive), outperforming the IXFH18N100Q3's 660mΩ. This 36% reduction in conduction losses directly improves overall efficiency, reduces heat generation in high-frequency switching applications, and lowers cooling system design pressure and energy costs.
Additionally, the VBP110MR24 supports a ±30V gate-source voltage, providing stronger gate ESD and noise immunity, preventing unintended turn-on in complex electromagnetic environments. The 3.5V gate threshold voltage balances driving convenience and switching reliability, seamlessly matching mainstream driver ICs without drive circuit adjustments, further lowering the substitution barrier.
Enhanced with Advanced Planar Gate Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the IXFH18N100Q3 lies in its low on-resistance and high switching performance. The VBP110MR24 employs industry-leading Planar gate technology, building upon the original model's switching characteristics while optimizing reliability across multiple dimensions. The device undergoes 100% avalanche testing and high-voltage screening before leaving the factory, exhibiting excellent single-pulse avalanche energy performance, easily handling energy surges during high-voltage turn-off and reducing avalanche breakdown risks. Through optimized intrinsic capacitance design, it reduces charge/discharge losses during switching and elevates dv/dt tolerance, perfectly matching IXFH18N100Q3 application scenarios. Even under harsh conditions like high-frequency switching and fast transients, it maintains stable operation without circuit topology changes. Furthermore, the VBP110MR24 features an ultra-wide operating temperature range, adapting to complex conditions such as industrial high-temperature environments and outdoor extremes. Having passed rigorous high-temperature/high-humidity aging tests and long-term reliability verification, its failure rate is below industry averages, ensuring long-term, uninterrupted operation—ideal for critical fields like medical equipment, industrial control, and emergency power supplies.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a core concern in domestic substitution is R&D investment and time costs. The VBP110MR24 addresses this through its package design. The device uses a TO-247 package, identical to the IXFH18N100Q3's standard package in pinout, pin spacing, dimensions, and heatsink structure. Engineers need not modify PCB layouts or thermal designs, achieving "plug-and-play" replacement. This high compatibility reduces substitution verification time—sample validation typically completes within 1-2 days—and avoids costs from PCB revisions or mold adjustments. It also preserves original product structures, eliminating re-certification needs, shortening supply cycles, and helping enterprises quickly achieve import substitution to seize market opportunities.
