In high-power, high-voltage application fields such as industrial switch-mode power supplies, motor drives, UPS systems, and solar inverters, Microchip's APT6025BFLLG has been widely adopted by engineers globally for its robust performance. However, in the context of persistent global supply chain uncertainties and extended lead times for imported components, sourcing this device often involves challenges such as unpredictable delays, cost volatility due to exchange rates, and limited local technical support. These factors increasingly impact production planning and cost efficiency for downstream manufacturers. Consequently, domestic substitution has evolved from a strategic consideration to an operational imperative, offering a reliable path to enhance supply chain resilience and competitiveness.
Leveraging its extensive expertise in power semiconductor design and manufacturing, VBsemi introduces the VBP16R26S—an N-channel power MOSFET developed through independent R&D as a high-performance, pin-to-pin alternative to the APT6025BFLLG. With upgraded key parameters, advanced technology, and full package compatibility, the VBP16R26S enables seamless replacement without circuit modification, delivering a more stable, cost-effective, and locally supported solution for demanding high-power applications.
Enhanced Electrical Parameters Provide Greater Design Margin and Efficiency
Designed as a direct replacement for the APT6025BFLLG, the VBP16R26S demonstrates meaningful improvements in several critical specifications, ensuring reliable operation under rigorous conditions:
The device maintains a drain-source voltage rating of 600V, matching the original part, while delivering a significantly lower on-state resistance of just 115mΩ (measured at VGS=10V)—a 23% reduction compared to the APT6025BFLLG's 150mΩ. This reduction directly lowers conduction losses, improves system efficiency, and reduces thermal dissipation, easing thermal management demands.
Although the continuous drain current is rated at 26A compared to the original 31A, the optimized RDS(on) and advanced packaging ensure robust current-handling capability suitable for most high-power applications. The VBP16R26S also features a gate-source voltage range of ±30V, offering enhanced gate durability and noise immunity in electrically noisy environments. With a standard gate threshold voltage of 3.5V, the device remains fully compatible with common driver ICs, enabling easy integration without drive circuit redesign.
Advanced SJ_Multi-EPI Technology Ensures High Reliability and Switching Performance
The APT6025BFLLG relies on advanced trench technology for low resistance and fast switching. The VBP16R26S employs VBsemi's proprietary SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology, which achieves an optimal balance between low on-resistance and high switching speed. This design reduces switching losses, improves dv/dt immunity, and enhances overall reliability in high-frequency circuits.
Each VBP16R26S undergoes rigorous pre-shipment validation, including 100% avalanche energy testing, ensuring consistent performance under voltage transients and inductive switching conditions. The device supports an operating temperature range from -55°C to 150°C and has passed extended reliability tests such as high-temperature reverse bias (HTRB) and high-humidity high-temperature reverse bias (H3TRB), making it suitable for industrial, automotive, and outdoor applications where operational stability is critical.
Full Package Compatibility Enables Drop-In Replacement
The VBP16R26S is offered in the industry-standard TO-247 package, which is mechanically and electrically identical to the APT6025BFLLG's TO-247 footprint. This complete pin-to-pin and footprint compatibility allows engineers to replace the existing component without any PCB layout changes, heatsink modifications, or system revalidation. The “plug-and-play” substitution significantly reduces qualification time, minimizes re-engineering costs, and accelerates time-to-market for upgraded or new designs.
Local Supply Chain and Responsive Technical Support
Unlike imported alternatives subject to international logistics and geopolitical disruptions, VBsemi manufactures the VBP16R26S in its fully controlled production facilities within China. This localized supply chain ensures stable inventory, short lead times (typically within 2–3 weeks), and consistent quality. Emergency order support and expedited shipping options are available to meet urgent production needs.
VBsemi’s technical support team provides comprehensive assistance throughout the design and replacement process, including substitution guidance, thermal design recommendations, application notes, and circuit analysis. Customers benefit from direct communication, fast response times, and ongoing engineering support—effectively eliminating the traditional barriers associated with substituting imported power devices.
From industrial motor drives and high-density power supplies to renewable energy systems and welding equipment, the VBP16R26S stands out as a reliable, high-performance domestic alternative to the APT6025BFLLG. With its lower conduction losses, robust switching characteristics, full compatibility, and locally secured supply, the VBP16R26S enables manufacturers to enhance product performance while strengthening supply chain autonomy—all without compromising reliability or requiring redesign efforts.
