In high-power switching applications such as industrial motor drives, power supplies, inverters, welding equipment, and renewable energy systems, Littelfuse IXYS's IXFH16N50P, with its international standard package, unclamped inductive switching (UIS) rating, low package inductance, and high power density, has been a trusted solution for engineers globally. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component faces challenges: extended lead times (often several months), cost volatility due to exchange rates, and delayed technical support. These issues hinder production schedules and cost optimization for downstream enterprises. Consequently, domestic substitution has evolved from an "option" to a "necessity," offering a critical path to secure supply chains, reduce costs, and enhance competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBP15R50S N-channel power MOSFET through independent R&D. This product directly对标es the IXFH16N50P, delivering core advantages of parameter enhancement, technological parity, and full package compatibility. It serves as a drop-in replacement without circuit modifications, providing a more reliable, cost-effective, and locally supported solution for high-power electronic systems.
Comprehensive Parameter Advancement, Enhanced Performance Margins, Adapting to Demanding Conditions.
Tailored as a domestic alternative to the IXFH16N50P, the VBP15R50S achieves significant, leapfrog improvements in key electrical parameters, ensuring robust performance for high-power applications:
First, the continuous drain current is dramatically increased to 50A, surpassing the original model's 16A—a 212.5% enhancement in current-carrying capacity. This enables seamless adaptation to higher-power circuit designs, whether upgrading existing systems or improving stability at similar power levels.
Second, the on-state resistance is reduced to 80mΩ (@10V gate drive), a substantial improvement over the IXFH16N50P's 400mΩ. This 80% reduction in RDS(on) significantly lowers conduction losses, boosting overall system efficiency. In high-frequency switching scenarios, it minimizes heat generation, easing thermal design constraints and reducing cooling costs.
Third, the drain-source voltage maintains 500V, matching the original model while ensuring reliability in standard high-voltage environments. The VBP15R50S supports a ±30V gate-source voltage, offering enhanced gate ESD protection and noise immunity, preventing false triggering in complex electromagnetic conditions. The 3.8V gate threshold voltage balances drive convenience and switching reliability, seamlessly兼容 with mainstream driver ICs without requiring drive circuit adjustments, simplifying substitution.
Empowered by Advanced SJ_Multi-EPI Technology, Reliability and Stability Elevated.
The IXFH16N50P excels with features like UIS rating and low package inductance. The VBP15R50S employs state-of-the-art SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology, building on the original's strengths while optimizing device reliability. It undergoes rigorous avalanche testing and high-voltage screening, exhibiting excellent UIS performance to handle energy surges during switching, reducing failure risks. Through optimized intrinsic capacitance design, it minimizes switching losses and enhances dv/dt tolerance, ensuring stable operation under high-frequency or transient conditions—perfectly matching IXFH16N50P applications. Additionally, the VBP15R50S operates over a wide temperature range of -55°C to 150°C, suitable for harsh industrial and outdoor environments. It has passed extended reliability tests, including high-temperature/high-humidity aging, with a failure rate below industry averages, providing dependable performance for critical applications like industrial automation, renewable energy, and medical devices.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement with Zero Hassle.
For downstream enterprises, a key concern in domestic substitution is the R&D effort and time investment. The VBP15R50S addresses this through its package design. It uses a TO-247 package, identical to the IXFH16N50P in pinout, pin spacing, dimensions, and heatsink compatibility. Engineers can replace the component without modifying PCB layouts or thermal designs, achieving true "plug-and-play" convenience. This high compatibility reduces verification time—sample validation typically completes within 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 enabling swift import substitution to capture market opportunities.
