In various high-voltage, high-frequency application scenarios such as switch-mode power supplies, industrial inverters, LED lighting drivers, welding machines, and UPS systems, Toshiba's TK17N65W,S1F, with its robust performance and reliable design, has been a preferred choice for engineers worldwide. 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), procurement costs vulnerable to exchange rate fluctuations, and delayed technical support. These issues hinder production schedules and cost control for downstream companies. Consequently, domestic substitution has evolved from an option to a necessity, offering a critical path to enhance supply chain security, reduce costs, and improve competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBP16R15S N-channel power MOSFET, developed through independent R&D. This product is precisely aligned with the TK17N65W,S1F, offering core advantages of parameter compatibility, technological advancement, and full package compatibility. It serves as a direct drop-in replacement without circuit modifications, delivering a stable, cost-effective, and locally supported solution for high-voltage electronic systems.
Optimized Parameter Matching, Enhanced Reliability for Demanding Conditions.
Designed as a domestic alternative to the TK17N65W,S1F, the VBP16R15S provides reliable performance with key electrical parameters tailored for high-voltage applications:
The drain-source voltage is rated at 600V, ensuring sufficient margin for many industrial environments with stable grid requirements, while maintaining robust overvoltage protection capabilities. The continuous drain current is 15A, offering ample current-carrying capacity for a wide range of high-power designs, supporting stable operation in circuits such as inverters and motor drives. The on-state resistance is 280mΩ (@10V gate drive), facilitating low conduction losses and improved system efficiency, which helps reduce heat generation and cooling system demands in high-frequency switching applications. Additionally, the VBP16R15S supports a ±30V gate-source voltage, enhancing 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, simplifying drive circuit design and lowering substitution barriers.
Advanced SJ_Multi-EPI Technology, Delivering Superior Reliability and Stability.
While the TK17N65W,S1F relies on proven technology for performance, the VBP16R15S incorporates VBsemi's proprietary SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology, optimizing device reliability and switching characteristics. This technology enables excellent avalanche energy handling and high dv/dt tolerance, ensuring stable operation during high-voltage turn-off and fast transients. The device undergoes rigorous pre-shipment testing, including 100% avalanche and high-voltage screening, and excels in single-pulse avalanche energy performance. Through optimized intrinsic capacitance design, it reduces switching losses and enhances overall efficiency. Furthermore, the VBP16R15S operates over an ultra-wide temperature range of -55°C to 150°C, adapting to harsh industrial and outdoor conditions. It has passed extended reliability tests such as 1000-hour high-temperature/high-humidity (85°C/85% RH) aging, with a failure rate below industry averages, providing solid assurance for long-term use in critical applications like industrial control, medical equipment, and emergency power systems.
Fully Compatible Package, Enabling Seamless and Risk-Free Replacement.
For downstream enterprises, a major concern in domestic substitution is the R&D effort and time required. The VBP16R15S addresses this through its package design. It uses a TO247 package, identical to the TK17N65W,S1F in pinout, pin spacing, dimensions, and heatsink interface. Engineers can achieve "plug-and-play" replacement without modifying PCB layouts or thermal designs. This high compatibility reduces verification time—sample validation typically completes within 1-2 days—and avoids costs associated with PCB revisions or mold adjustments. It also preserves original product certifications and外观 designs, accelerating the substitution process and helping enterprises quickly upgrade imported components to capture market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Technical Support.
Unlike imported components affected by international logistics, trade policies, and currency fluctuations, VBsemi leverages China's mature semiconductor ecosystem, with modern production bases and R&D centers in Jiangsu, Guangdong, and other regions. This ensures full-process control and stable mass production for the VBP16R15S. Current standard lead times are within 2 weeks, with emergency orders supporting 72-hour rapid delivery, mitigating risks from supply chain volatility, tariffs, and geopolitics. As a local brand, VBsemi provides dedicated technical support with "one-on-one" services: comprehensive documentation including substitution验证 reports, datasheets, thermal design guides, and application circuit references, plus tailored selection advice and circuit optimization based on customer scenarios. Technical issues receive responses within 24 hours, with on-site or remote assistance, eliminating the slow response and high communication costs of imported components and ensuring a smooth substitution experience.
From industrial switch-mode power supplies and high-frequency inverters to LED lighting drivers and welding machines; from UPS systems and motor drives to new energy charging equipment, the VBP16R15S, with its core advantages of "parameter compatibility, reliable performance, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the TK17N65W,S1F. It has been adopted by leading companies across multiple industries, earning strong market recognition. Choosing the VBP16R15S is not merely a component swap—it is a strategic move to upgrade supply chain security, optimize production costs, and enhance product competitiveness, offering superior value without R&D modification risks.
