In high-performance automotive electronic systems such as motor drives, power management units, LED lighting, and DC-DC converters, Nexperia's BUK9Y22-100E,115, with its advanced TrenchMOS technology, logic-level design, and AEC Q101 certification, has been a trusted choice for engineers worldwide in automotive-grade applications. However, in the context of global supply chain uncertainties and trade tensions, this imported component faces challenges like extended lead times, cost volatility due to exchange rates, and delayed technical support, which can disrupt production schedules and increase costs for automotive manufacturers. As a result, domestic substitution has evolved from an alternative to a necessity, offering a strategic path to enhance supply chain resilience, reduce costs, and boost competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBED1101N N-channel MOSFET, developed through independent R&D to precisely match and surpass the BUK9Y22-100E,115. This product offers key advantages in parameter upgrades, technological parity, and full package compatibility, enabling direct replacement without circuit modifications. It provides a more stable, cost-effective, and locally supported solution for demanding automotive and industrial systems.
Comprehensive Parameter Enhancement, Superior Performance for Demanding Conditions.
Tailored as a domestic alternative to the BUK9Y22-100E,115, the VBED1101N achieves significant improvements in critical electrical parameters, delivering robust performance for high-current applications:
First, the drain-source voltage is maintained at 100V, matching the original model's rating, ensuring compatibility in standard automotive voltage environments while providing reliable operation under typical load conditions.
Second, the continuous drain current is boosted to 69A, a substantial 40.8% increase over the original model's 49A. This enhancement allows for handling higher power loads with ease, supporting more demanding applications such as high-power motor drives or upgraded system designs without compromising stability.
Third, the on-state resistance is drastically reduced to 11.6mΩ (@10V gate drive), significantly lower than the BUK9Y22-100E,115's 22mΩ (@5V, 15A). This reduction minimizes conduction losses, improving overall system efficiency and reducing heat generation—critical for automotive applications where thermal management is essential for reliability and longevity.
Additionally, the VBED1101N supports a ±20V gate-source voltage, offering enhanced ESD protection and noise immunity in electrically noisy automotive environments. The 1.4V gate threshold voltage facilitates easy driving with standard logic-level controllers, ensuring seamless integration with existing automotive ECUs without requiring drive circuit adjustments.
Advanced Trench Technology, Elevating Reliability and Automotive Compliance.
The BUK9Y22-100E,115 relies on TrenchMOS technology for low on-resistance and efficient switching. The VBED1101N employs an optimized Trench process, building on this foundation while enhancing device reliability. It is designed and certified according to AEC Q101 standards, ensuring suitability for rigorous automotive applications. The device undergoes comprehensive testing, including high-temperature and high-humidity aging tests, to guarantee performance under extreme conditions such as engine compartments or outdoor environments. With an operational temperature range from -55°C to 150°C, it withstands automotive thermal cycles and transient surges, reducing failure risks and supporting long-term, maintenance-free operation in critical systems like electric power steering, braking, and infotainment.
Fully Compatible Package, Enabling Seamless Drop-In Replacement.
To simplify the substitution process, the VBED1101N features an LFPAK56 (Power SO8) package identical to the BUK9Y22-100E,115 in pinout, dimensions, and thermal pad layout. Engineers can directly replace the original component on the PCB without redesigning the layout or thermal management system, achieving "plug-and-play" integration. This compatibility slashes verification time—typically to 1-2 days for sample testing—and avoids additional costs from board revisions or tooling changes. It ensures that existing product certifications and外观 designs remain valid, accelerating time-to-market for automotive upgrades.
Localized Strength, Ensuring Supply Chain Stability and Responsive Support.
Unlike imported components prone to logistics delays and geopolitical risks, VBsemi leverages domestic semiconductor infrastructure with production bases in Jiangsu and Guangdong, enabling full control over VBED1101N manufacturing. Standard lead times are compressed to under two weeks, with expedited orders available for 72-hour delivery, mitigating supply chain disruptions. As a local brand, VBsemi provides dedicated technical support, including detailed substitution reports, datasheets, thermal guidelines, and application notes. The technical team offers rapid, 24-hour response for any issues, assisting with on-site or remote troubleshooting—addressing the slow support and high communication costs often associated with imported parts.
From automotive motor drives and power systems to industrial inverters and LED drivers, the VBED1101N, with its core advantages of "higher current capability, lower conduction loss, package compatibility, secure supply, and localized service," has become the preferred domestic alternative to the BUK9Y22-100E,115. It is already adopted by leading automotive suppliers, gaining strong market recognition. Choosing the VBED1101N is not just a component swap; it is a strategic move to fortify supply chains, optimize costs, and enhance product reliability—requiring no design risks while benefiting from superior performance, stable supply, and prompt technical support.
