In various low-voltage, high-current application scenarios such as automotive systems, server power supplies, motor drives, and high-density DC-DC converters, NXP's BUK7C10-75AITE,118, with its low on-resistance and high current capability, has been a key component for engineers worldwide. However, amidst global supply chain uncertainties and procurement challenges, this imported part often faces issues like extended lead times and cost volatility. This drives the urgent need for a reliable, high-performance domestic alternative to secure production and optimize costs.
VBsemi, leveraging its deep expertise in power semiconductors, introduces the VBGL7802 N-channel MOSFET based on independent R&D. This product serves as a direct substitute for the BUK7C10-75AITE,118, offering superior parameters, advanced technology, and full package compatibility, enabling a seamless replacement without circuit modifications and providing a more robust, cost-effective solution for demanding low-voltage systems.
Comprehensive Parameter Advancement, Enhanced Performance Headroom for Demanding Applications.
Designed as a domestic alternative to the BUK7C10-75AITE,118, the VBGL7802 achieves significant improvements across key electrical specifications, delivering stronger performance and reliability:
First, the drain-source voltage is increased to 80V, higher than the original 75V, providing an extra safety margin in environments with voltage spikes or transients.
Second, the continuous drain current is dramatically raised to 250A, far exceeding the original 50A. This leapfrog enhancement in current-handling capability effortlessly supports higher power designs and improves system stability.
Third, the on-state resistance is reduced to an ultra-low 1.7mΩ (@10V gate drive), significantly lower than the original 10mΩ. This minimizes conduction losses, boosts efficiency, and reduces thermal stress, easing cooling requirements.
Additionally, the VBGL7802 supports a ±20V gate-source voltage, ensuring strong gate robustness against ESD and noise. The 3.5V typical gate threshold voltage ensures compatibility with mainstream driver ICs, requiring no drive circuit adjustments.
Advanced SGT Technology, Delivering Superior Switching Performance and Reliability.
The BUK7C10-75AITE,118 relies on advanced trench technology for low resistance. The VBGL7802 employs VBsemi’s proprietary Shielded Gate Trench (SGT) technology, which further optimizes switching characteristics and reliability. The SGT structure reduces gate charge and switching losses, enabling higher frequency operation and improved efficiency. The device undergoes rigorous avalanche testing and screening, ensuring high robustness against transient energy surges. With an optimized internal capacitance design, it achieves excellent dv/dt immunity, matching or exceeding the original part’s performance in high-speed switching applications. The VBGL7802 also operates reliably across a wide temperature range and has passed stringent reliability tests, making it suitable for automotive, industrial, and high-reliability applications.
Fully Compatible Package, Enabling Direct Drop-In Replacement.
The VBGL7802 uses a TO263-7L package, which is pin-to-pin and footprint compatible with the BUK7C10-75AITE,118. This allows engineers to replace the component directly on the existing PCB without any layout changes or thermal redesign. The seamless compatibility drastically reduces substitution time and cost—verification can typically be completed within days, avoiding expensive PCB re-spins and requalification efforts. This “plug-and-play” approach enables rapid supply chain switching with minimal risk.
Local Supply Chain Assurance, Stable Delivery and Responsive Support.
Unlike imported components susceptible to global logistics and trade uncertainties, VBsemi manufactures the VBGL7802 within a robust domestic semiconductor ecosystem. With modern production facilities in China, VBsemi ensures stable mass production and short lead times, typically within weeks. Emergency order support enables rapid delivery, mitigating supply chain disruptions. As a local supplier, VBsemi provides dedicated technical support, including comprehensive documentation, substitution guides, and application assistance. The engineering team offers prompt responses and tailored solutions, eliminating the slow support cycles often associated with international brands.
From automotive power systems and server SMPS to motor drives and high-current DC-DC modules, the VBGL7802, with its superior parameters, advanced SGT technology, package compatibility, and reliable local supply, stands as the ideal domestic alternative to the BUK7C10-75AITE,118. It has already been adopted by leading customers across industries, earning strong market validation. Choosing the VBGL7802 is not just a component substitution—it is a strategic step toward securing your supply chain, reducing costs, and enhancing product performance without design risks.
