In high-efficiency switching power applications such as Power Factor Correction (PFC), server & telecom power supplies, FPD TV power supplies, ATX power supplies, and industrial power systems, onsemi's FCH077N65F-F155, with its advanced SuperFET II technology utilizing charge balance for low on-resistance and superior switching performance, has been a preferred component for designers seeking optimal efficiency and robustness. However, navigating the complexities of global supply chains, extended lead times, and cost volatility poses significant challenges for production stability and cost management. This reality elevates domestic substitution from a strategic consideration to an operational imperative, crucial for ensuring supply chain resilience and enhancing product competitiveness.
Leveraging deep expertise in power semiconductor innovation, VBsemi introduces the VBP16R67S N-channel MOSFET, a precisely engineered domestic alternative to the FCH077N65F-F155. This product delivers core advantages of enhanced electrical parameters, technological parity, and full package compatibility, enabling a direct, drop-in replacement that offers a more reliable, cost-effective, and locally-supported solution for demanding high-voltage applications.
Comprehensive Parameter Advancement, Delivering Higher Efficiency and Power Density
Designed as a high-performance substitute, the VBP16R67S achieves significant, leapfrog improvements in key specifications, providing superior margins for next-generation designs:
- Voltage & Current Robustness: With a drain-source voltage (VDS) of 600V, it matches the high-voltage requirements of industrial and telecom environments. More notably, its continuous drain current (ID) is rated at 67A, a substantial 24% increase over the original 54A, enabling support for higher power levels and improved operational stability.
- Significantly Reduced Conduction Losses: The on-state resistance (RDS(on)) is dramatically lowered to 34mΩ (at 10V VGS), compared to the FCH077N65F-F155's 77mΩ. This 56% reduction in RDS(on) directly minimizes conduction losses, boosting system efficiency and reducing thermal dissipation, which simplifies heatsink design and lowers energy costs.
- Enhanced Drive Compatibility: The device supports a gate-source voltage (VGS) of ±30V, offering robust protection against gate noise and ESD events. The 3.5V gate threshold voltage (Vth) ensures reliable switching and seamless compatibility with mainstream driver ICs, requiring no circuit modifications.
Advanced SJ_Multi-EPI Technology, Ensuring Superior Switching Reliability and Ruggedness
The FCH077N65F-F155 leverages SuperFET II technology for excellent switching performance and avalanche energy capability. The VBP16R67S employs VBsemi's proprietary SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology, which not only maintains the benefits of low gate charge and high dv/dt tolerance but also pushes the boundaries of efficiency and ruggedness.
This optimized structure reduces switching losses and enhances body diode reverse recovery characteristics, making it ideal for high-frequency hard- and soft-switching topologies. The device undergoes rigorous avalanche energy and high-voltage screening, ensuring exceptional durability against voltage spikes and transient energy surges. With an operating junction temperature range from -55°C to 150°C and validated through extended reliability testing (including HTGB/H3TRB), the VBP16R67S offers outstanding long-term stability for critical applications in industrial, communications, and energy infrastructure.
Fully Compatible TO-247 Package, Enabling Seamless Drop-In Replacement
To eliminate redesign efforts and accelerate time-to-market, the VBP16R67S is offered in a standard TO-247 package. It is mechanically and pin-to-pin identical to the FCH077N65F-F155, requiring no changes to PCB layout, thermal design, or assembly process. This "plug-and-play" compatibility allows engineers to validate the substitution within days, avoiding costly PCB respins, retooling, and requalification cycles. The seamless replacement minimizes risk, reduces downtime, and enables rapid supply chain transition.
Localized Supply Chain and Expert Technical Support, Providing Dual Assurance
Unlike imported components susceptible to logistics delays, geopolitical factors, and cost fluctuations, VBsemi's domestic manufacturing base ensures a stable, responsive supply for the VBP16R67S. Standard lead times are reliably shortened, with expedited support available for urgent needs, thereby shielding customers from external supply chain disruptions.
Complementing this supply security, VBsemi's local technical team provides dedicated, responsive application support. From comprehensive substitution guides and detailed datasheets to thermal modeling advice and circuit optimization, customers receive tailored assistance.
