In various high-current, low-voltage application scenarios such as motor drives, power supplies, automotive systems, industrial controls, and battery management, MCC's MCAC100N08Y-TP, with its split-gate trench MOSFET technology, excellent thermal package design, and high-density cell structure for low RDS(on), has long been a key choice for engineers globally. However, against the backdrop of post-pandemic global supply chain disruptions and frequent trade frictions, this imported component increasingly reveals pain points: unstable lead times (often extending to months), procurement costs vulnerable to exchange rate fluctuations, and slow technical support responses. These issues severely constrain downstream companies' production efficiency and cost control. Given this demand, domestic substitution has shifted 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 deep expertise in power semiconductors, has launched the VBGQA1803 N-channel power MOSFET based on independent R&D. This product precisely对标es the MCAC100N08Y-TP, offering core advantages of parameter upgrades, technological parity, and package compatibility. It serves as a direct drop-in replacement without any circuit modifications, delivering a more stable, cost-effective, and locally attuned high-quality solution for various high-current electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the MCAC100N08Y-TP, the VBGQA1803 achieves across-the-board, leapfrog improvements in key electrical parameters, providing robust performance guarantees for high-current applications:
Firstly, the drain-source voltage is maintained at 80V, ensuring full compatibility with the original model's rating, while offering a reliable foundation for low-voltage, high-current designs.
Secondly, the continuous drain current is significantly increased to 140A, a 40% enhancement over the original model's 100A. This substantial boost in current-carrying capability allows effortless adaptation to higher-power circuit requirements, whether upgrading existing equipment or improving system stability under heavy loads.
Thirdly, the on-state resistance is as low as 2.65mΩ (@10V gate drive), markedly superior to the MCAC100N08Y-TP's 4.5mΩ. This reduction minimizes conduction losses, directly enhancing overall system efficiency and reducing heat generation—particularly beneficial in high-frequency switching applications, where it lowers cooling system demands and energy costs.
Additionally, the VBGQA1803 supports a ±20V gate-source voltage, offering enhanced gate ESD protection and noise immunity, preventing unintended turn-on in complex electromagnetic environments. The 3.5V gate threshold voltage balances driving convenience and switching reliability, seamlessly matching mainstream driver ICs without requiring drive circuit adjustments, further simplifying substitution.
Enhanced with Advanced SGT (Split-Gate Trench) Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the MCAC100N08Y-TP lies in the low RDS(on) and high efficiency delivered by its split-gate trench MOSFET technology. The VBGQA1803 employs advanced SGT technology, building upon the original model's strengths while optimizing device reliability across multiple dimensions. The device undergoes rigorous pre-shipment testing, including 100% avalanche and thermal screening, exhibiting excellent single-pulse avalanche energy performance. It reliably handles energy surges during switching, reducing the risk of avalanche-induced damage. Through optimized intrinsic capacitance design, it not only lowers switching losses but also improves dv/dt tolerance, perfectly matching the MCAC100N08Y-TP's application scenarios. Even under harsh conditions like high-current surges and fast transients, it maintains stable operation. Furthermore, the VBGQA1803 features an ultra-wide operating temperature range, capable of withstanding industrial high-temperature environments and extreme climates. Having passed extended reliability tests such as high-temperature/humidity aging, its failure rate is well below industry averages, providing solid assurance for long-term, uninterrupted operation—ideally suited for critical fields like automotive, industrial automation, and energy storage.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a primary concern in domestic substitution is the R&D investment and time costs involved. The VBGQA1803 addresses this through its package design. The device uses a compact DFN8(5X6) package, optimized for high-density layouts and excellent thermal performance. While pinout and dimensions are tailored for modern designs, engineers can easily adapt it to existing PCB layouts with minimal adjustments, achieving a "plug-and-play" replacement experience. This compatibility significantly reduces verification time—sample validation can typically be completed within 1-2 days—and avoids costs associated with major PCB revisions or mold changes. It ensures seamless integration into original product structures, eliminating re-certification needs and accelerating time-to-market, helping enterprises swiftly achieve import substitution and capture market opportunities.
