In various high-performance automotive application scenarios such as motor drives, power supply systems, LED lighting, and battery management, Nexperia's BUK7Y7R8-80EX, with its advanced TrenchMOS technology, AEC Q101 certification, and low on-resistance, has long been a preferred choice for engineers worldwide in design selection. However, in the context of global supply chain challenges and trade uncertainties, this imported component increasingly reveals pain points: unpredictable lead times, procurement costs affected by currency fluctuations, and delayed technical support. These issues hinder production schedules and cost control for automotive manufacturers. Given this industry demand, domestic substitution has evolved from an "option" to a "necessity," becoming a critical path for ensuring supply chain security, reducing costs, and enhancing competitiveness.
VBsemi, leveraging years of expertise in power semiconductors, introduces the VBED1806 N-channel MOSFET based on independent R&D. This product precisely对标es the BUK7Y7R8-80EX, offering core advantages of parameter enhancements, 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 tailored solution for automotive electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance, Adapting to Demanding Automotive Conditions.
Tailored as a domestic alternative to the BUK7Y7R8-80EX, the VBED1806 achieves significant improvements in key electrical parameters, delivering robust performance for automotive applications:
First, the drain-source voltage is maintained at 80V, matching the original model, ensuring compatibility in standard automotive voltage environments. Second, the continuous drain current is rated at 90A, slightly below the original 100A but optimized for enhanced efficiency and thermal management, offering reliable current-carrying capacity for most high-power circuits. Third, the on-state resistance is reduced to 6mΩ (@10V gate drive), outperforming the BUK7Y7R8-80EX's 7.8mΩ—a 23% reduction. This lowers conduction losses, improves system efficiency, and reduces heat generation, critical for automotive thermal design. Additionally, the VBED1806 supports a ±20V gate-source voltage, providing strong gate ESD and noise immunity, while the 1.4V gate threshold voltage ensures easy drive compatibility with mainstream automotive driver ICs, simplifying substitution.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The core strength of the BUK7Y7R8-80EX lies in its TrenchMOS technology for low on-resistance and high switching performance. The VBED1806 employs optimized Trench technology, building on the original model's advantages while improving reliability. The device undergoes rigorous testing, including AEC Q101 qualification, ensuring exceptional performance under automotive stress conditions. Through refined capacitance design, it reduces switching losses and enhances dv/dt tolerance, maintaining stable operation in high-frequency automotive environments like motor drives and DC-DC converters. The VBED1806 operates over a wide temperature range of -55°C to 150°C, suitable for harsh automotive conditions such as engine compartments and extreme climates. It has passed extended reliability tests, including high-temperature and humidity aging, with a failure rate below industry averages, making it ideal for safety-critical automotive applications like electric vehicles, ADAS, and infotainment systems.
Fully Compatible Package, Enabling "Seamless, Risk-Free, and Immediate" Replacement.
For automotive manufacturers, a key concern in domestic substitution is the R&D effort and time involved. The VBED1806 addresses this through its package design. The device uses an LFPAK56 (Power SO8) package, identical to the BUK7Y7R8-80EX in pinout, dimensions, and thermal structure. Engineers can directly replace the component without PCB layout changes or thermal system adjustments, achieving "plug-and-play" convenience. This high compatibility reduces verification time—sample validation can be completed in 1-2 days—and avoids costs from redesign or recertification. It streamlines the supply chain, enabling quick adoption of domestic alternatives and faster time-to-market.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to imported components with volatile supply chains, VBsemi utilizes China's robust semiconductor ecosystem, with modern production bases in Jiangsu and Guangdong, ensuring full-process control and stable mass production of the VBED1806. Lead times are compressed to under 2 weeks, with emergency orders supporting 72-hour delivery, mitigating risks from global logistics, tariffs, or geopolitics. As a local brand, VBsemi offers dedicated technical support: comprehensive documentation including substitution reports, datasheets, thermal guides, and application circuits, plus tailored advice based on customer needs. Technical issues receive responses within 24 hours, resolving pain points like slow support and high communication costs, making substitution smooth and worry-free.
From motor drives and power supplies to LED lighting and battery systems; from automotive infotainment to electric vehicle charging, the VBED1806, with its core advantages of "superior parameters, enhanced reliability, package compatibility, controllable supply, and responsive service," has become the preferred domestic alternative to the BUK7Y7R8-80EX. It is already adopted by leading automotive companies, gaining market recognition. Choosing the VBED1806 is not just a component swap—it's a strategic move to upgrade supply chain security, optimize costs, and boost product competitiveness, offering better performance, stable supply, and seamless support without R&D risks.
