In various medium-voltage, high-current application scenarios such as power supplies, motor drives, DC-DC converters, and industrial controls, NXP's BUK9510-100B,127, with its advanced TrenchMOS technology, low on-resistance, and high current-handling capability, has been a key component for engineers worldwide during design selection. However, in the context of global supply chain uncertainties and trade tensions, this imported part has revealed significant pain points: extended lead times, procurement costs vulnerable to exchange rate swings, and delayed technical support. These issues constrain production schedules and cost control for downstream companies. Given this demand, domestic substitution has evolved from an "option" to a "necessity," becoming a critical path for enterprises to ensure supply chain security, reduce costs, and enhance competitiveness.
VBsemi, leveraging years of expertise in power semiconductors, introduces the VBM1101N N-channel power MOSFET based on independent R&D. This product precisely aligns with the BUK9510-100B,127, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It serves as a direct drop-in replacement without circuit modifications, providing a more stable, cost-effective, and locally supported solution for various medium-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance, Adapting to Demanding Conditions.
Tailored as a domestic alternative to the BUK9510-100B,127, the VBM1101N achieves significant improvements in key electrical parameters, delivering robust performance for medium-voltage applications:
Firstly, the continuous drain current is increased to 100A, substantially surpassing the original model's 75A—a 33% enhancement in current-carrying capacity. This enables effortless handling of higher power loads, whether upgrading existing equipment or improving system stability at similar power levels.
Secondly, the on-state resistance is as low as 9mΩ (@10V gate drive), better than the BUK9510-100B,127's 10mΩ (@5V). This reduction minimizes conduction losses, boosting overall efficiency and reducing heat generation in high-current applications, thereby easing thermal design pressures.
Additionally, the VBM1101N supports a ±20V gate-source voltage, offering strong gate ESD and noise immunity, preventing unintended turn-on in noisy environments. The 2.5V gate threshold voltage balances drive convenience and switching reliability, seamlessly matching mainstream driver ICs without circuit adjustments.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The BUK9510-100B,127 benefits from TrenchMOS technology for low on-resistance and fast switching. The VBM1101N employs optimized Trench gate process, building on these strengths while enhancing device reliability. It undergoes rigorous testing, including avalanche and high-voltage screening, ensuring excellent performance under surge conditions. Through refined capacitance design, it reduces switching losses and improves dv/dt tolerance, matching the original model's scenarios. The device operates over a wide temperature range of -55°C to 150°C, suitable for harsh industrial environments. Having passed long-term reliability tests, its failure rate is below industry averages, ideal for critical applications like motor drives and power systems.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
The VBM1101N addresses replacement concerns with its package design. It uses a TO-220 package, identical to the BUK9510-100B,127 in pinout, spacing, dimensions, and heatsink structure. Engineers need no PCB or thermal design changes, enabling immediate replacement. This compatibility slashes verification time—sample validation typically completes in 1-2 days—and avoids costs from redesigns, ensuring quick supply chain integration.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Support.
Compared to volatile imported supply chains, VBsemi utilizes China's robust semiconductor ecosystem, with production and R&D bases in Jiangsu and Guangdong, ensuring full-process control and stable mass production. Lead times for the VBM1101N are compressed to under 2 weeks, with expedited options for 72-hour delivery, mitigating risks from tariffs, logistics, and geopolitics. As a local brand, VBsemi provides dedicated technical support: comprehensive documentation (substitution reports, datasheets, thermal guides), scenario-specific advice, and 24-hour response for issues, eliminating slow support and high communication costs of imported parts.
From power supplies and motor drives to industrial controls and automotive systems, the VBM1101N, with its "superior parameters, stable performance, package compatibility, controllable supply, and attentive service," is the preferred domestic alternative to the BUK9510-100B,127. It has gained market recognition in leading companies. Choosing the VBM1101N is not just a component swap—it's a strategic move for supply chain security, cost optimization, and competitiveness, offering better performance, stable supply, and seamless support without R&D risks.
