In high-voltage switching applications such as power factor correction (PFC), server/telecom power supplies, flat-panel TV power supplies, ATX power supplies, and industrial power systems, onsemi's FCP11N60, with its first-generation SuperFET technology utilizing charge balance for low on-resistance and low gate charge, has been a preferred choice for engineers seeking efficient switching performance, high dv/dt capability, and avalanche energy. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component faces challenges: extended lead times (often several months), cost volatility due to exchange rates, and delayed technical support. These issues hinder production schedules and cost control for downstream companies. Against this backdrop, domestic substitution has evolved from an "option" to a "necessity," becoming a critical strategy for ensuring supply chain security, reducing costs, and enhancing competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBM16R11S N-channel power MOSFET through independent R&D. This product is precisely aligned to replace the FCP11N60, offering core advantages of parameter equivalence, technological parity, and full package compatibility. It serves as a direct drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for high-voltage electronic systems.
Comprehensive Parameter Matching, Enhanced Performance Reliability, Adapting to Demanding Conditions.
Tailored as a domestic alternative to the FCP11N60, the VBM16R11S achieves key electrical parameter matches with added reliability benefits for high-voltage applications:
First, the drain-source voltage is rated at 600V, providing sufficient margin for most industrial applications where grid fluctuations are managed, while maintaining compatibility with standard designs. The continuous drain current is 11A, matching the original model's 11A, ensuring robust current-carrying capacity for high-power circuits such as PFC and server power supplies.
Second, the on-state resistance is as low as 380mΩ (@10V gate drive), identical to the FCP11N60's 380mΩ. This low RDS(on) minimizes conduction losses, improving overall system efficiency and reducing heat generation in high-frequency switching scenarios, thereby easing thermal design constraints.
Additionally, the VBM16R11S supports a ±30V gate-source voltage, offering strong gate ESD and noise immunity to prevent unintended turn-on in complex electromagnetic environments. The 3.5V gate threshold voltage ensures compatibility with mainstream driver ICs, requiring no adjustments to drive circuits and simplifying substitution.
Advanced SJ_Multi-EPI Technology, Delivering Superior Reliability and Switching Performance.
The FCP11N60's core strength lies in its SuperFET technology with charge balance for low loss and high dv/dt tolerance. The VBM16R11S employs advanced SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology, building on similar principles to optimize device reliability. It features excellent low gate charge and fast switching characteristics, reducing switching losses and enhancing dv/dt tolerance for high-frequency applications like PFC and industrial power supplies. The device undergoes rigorous avalanche testing and high-voltage screening, ensuring high single-pulse avalanche energy capability to handle transient surges during turn-off. With an operating temperature range of -55°C to 150°C, it withstands harsh industrial environments and has passed long-term reliability tests, including high-temperature/high-humidity aging, resulting in a failure rate below industry averages. This makes it ideal for critical applications requiring durability, such as telecom power, medical equipment, and emergency systems.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement with Zero Risk.
For downstream enterprises, a major concern in domestic substitution is the R&D effort and time cost. The VBM16R11S addresses this through its package design. It uses a TO-220 package, fully compatible with the FCP11N60's TO-220 in pinout, pin spacing, dimensions, and heatsink structure. Engineers can replace the component without modifying PCB layouts or thermal designs, achieving seamless "plug-and-play" substitution. This high compatibility reduces verification time—sample validation can be completed in 1-2 days—and avoids costs associated with PCB revisions or retooling. It also preserves original product certifications and外观 designs, accelerating the supply chain cycle and helping enterprises quickly upgrade imported components to seize market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Technical Support.
Compared to imported components affected by international logistics, trade policies, and exchange rate fluctuations, VBsemi leverages China's robust semiconductor industry chain, with modern production bases and R&D centers in Jiangsu and Guangdong. This enables full-process independent R&D and stable mass production of the VBM16R11S. Current lead times are compressed to under 2 weeks, with expedited orders offering 72-hour delivery, mitigating risks from supply chain volatility, tariffs, and geopolitics. As a local brand, VBsemi provides a professional technical support team offering "one-on-one" customized services: comprehensive documentation including substitution verification reports, datasheets, thermal design guides, and application circuit references, plus tailored selection advice and circuit optimization based on customer scenarios. For any technical issues during substitution, the team responds within 24 hours for on-site or remote resolution, addressing the slow response and high communication costs of imported components, making the process smooth and worry-free.
From PFC circuits and server power supplies to industrial power systems and LED drivers; from ATX power supplies and welding machines to motor drives and new energy charging equipment, the VBM16R11S, with its core advantages of "parameter equivalence, reliable performance, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the FCP11N60. It has already been adopted by leading companies across multiple industries, gaining strong market recognition. Choosing the VBM16R11S is not just a component replacement—it is a strategic move for enterprises to upgrade supply chain security, optimize production costs, and enhance product competitiveness, offering superior performance, stable supply, and convenient support without R&D modification risks.
