In high-frequency switching and synchronous rectification applications such as server power supplies, telecom rectifiers, and high-density DC-DC converters, Infineon's IPB020N10N5, with its optimized FOMoss, extremely low on-resistance, and high-temperature operation up to 175°C, has been a preferred component for engineers worldwide. However, in the context of global supply chain uncertainties and fluctuating lead times, this imported part presents challenges including prolonged procurement cycles, cost volatility, and delayed technical support. These factors critically impact production scheduling and cost management for downstream manufacturers. Consequently, domestic substitution has evolved from an alternative to a necessity, serving as a strategic path to ensure supply chain resilience, reduce costs, and enhance product competitiveness.
Leveraging years of expertise in power semiconductor design, VBsemi introduces the VBGL1102 N-channel MOSFET based on its independent R&D capabilities. This product serves as a direct, pin-to-pin alternative to the IPB020N10N5, offering key advantages in upgraded parameters, advanced technology, and full package compatibility. It enables a seamless replacement without circuit modifications, providing a more reliable, cost-effective, and locally supported solution for high-current switching systems.
Comprehensive Parameter Enhancement, Delivering Higher Performance and Reliability.
Tailored as a domestic substitute for the IPB020N10N5, the VBGL1102 achieves significant improvements across critical electrical specifications, ensuring robust performance in demanding applications:
The continuous drain current is increased to 180A, surpassing the original 176A, thereby enhancing current-handling capability and supporting higher power density designs. The drain-source voltage is maintained at 100V, matching the original rating and ensuring compatibility in standard voltage applications. The on-state resistance is specified at 2.1mΩ (@10V gate drive), which is competitively low and optimized for reducing conduction losses, improving overall system efficiency, and minimizing thermal dissipation. The device supports a ±20V gate-source voltage, offering strong gate robustness and noise immunity in dynamic switching environments. The 3V gate threshold voltage ensures easy drive compatibility with mainstream controller ICs, requiring no circuit adjustments. Furthermore, the VBGL1102 operates over a wide temperature range, fully meeting the high-temperature demands of industrial environments.
Advanced SGT Technology, Optimized for Switching Performance and Reliability.
The IPB020N10N5 is known for its low RDS(on) and FOMoss optimization. The VBGL1102 employs VBsemi's proprietary Shielded Gate Trench (SGT) technology, which not only achieves low on-resistance but also significantly reduces gate charge and switching losses. This results in excellent Figure of Merit (FOM), making it ideal for high-frequency applications. The device undergoes rigorous reliability testing, including 100% avalanche energy testing and high-temperature operating life validation, ensuring stable performance under harsh conditions such as high-frequency switching, load transients, and thermal stress. Its enhanced dv/dt capability and robust intrinsic structure provide superior immunity to voltage spikes and ringing, ensuring long-term reliability in synchronous rectification and switch-mode power supplies.
Full Package Compatibility, Enabling Direct and Risk-Free Replacement.
A major concern in component substitution is the engineering effort required for redesign and validation. The VBGL1102 addresses this by offering complete mechanical and footprint compatibility. It is housed in a TO-263 package, which is identical to the IPB020N10N5 in pinout, dimensions, and mounting layout. Engineers can directly replace the existing component on the PCB without modifying the layout, thermal design, or mechanical assembly. This plug-and-play compatibility drastically reduces substitution time, eliminates redesign costs, and accelerates time-to-market. Validation can typically be completed within days, allowing for swift integration into existing production lines.
Local Supply Chain Assurance, Ensuring Stability and Responsive Support.
Unlike imported components subject to logistical delays and geopolitical risks, VBsemi's VBGL1102 is supported by a localized supply chain with modern manufacturing facilities in China. Standard lead times are shortened to within 2–3 weeks, with expedited options available for urgent needs. This ensures a stable and predictable supply, mitigating risks associated with international trade fluctuations. Additionally, VBsemi provides dedicated local technical support, including comprehensive documentation, substitution guidance, application notes, and circuit optimization assistance. The technical team offers rapid response, typically within 24 hours, to resolve any design or integration challenges, ensuring a smooth and worry-free transition.
From server and telecom power supplies to high-frequency DC-DC converters, motor drives, and synchronous rectification circuits, the VBGL1102 stands out as a superior domestic alternative to the IPB020N10N5. With its enhanced current capability, low conduction loss, advanced SGT technology, full package compatibility, and reliable local support, it has already been adopted by leading manufacturers across various industries. Choosing the VBGL1102 is not merely a component replacement—it is a strategic upgrade toward a more secure supply chain, lower total cost, and higher performance, without compromising on reliability or design effort.
