In various high-voltage, high-frequency application scenarios such as switch-mode power supplies, motor drives, industrial inverters, and lighting systems, Toshiba's TK290P60Y,RQ, with its robust performance and reliability, has been a trusted choice for engineers worldwide. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component faces challenges like 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 enterprises, making domestic substitution not just an option but a necessity for ensuring supply chain security, reducing costs, and enhancing competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBE16R15S N-channel power MOSFET through independent R&D. This product is precisely tailored as a domestic alternative to the TK290P60Y,RQ, offering advantages in parameter upgrades, technological parity, and full package compatibility. It serves as a direct replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for high-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance for Demanding Conditions.
Designed to replace the TK290P60Y,RQ, the VBE16R15S achieves significant improvements in key electrical parameters, providing robust performance for high-voltage applications:
First, the drain-source voltage remains at 600V, matching the original model, ensuring compatibility while maintaining reliability in environments with voltage fluctuations.
Second, the continuous drain current is increased to 15A, a substantial 30% upgrade over the original model's 11.5A, enabling higher power handling and improved stability in circuit designs.
Third, the on-state resistance is reduced to 240mΩ (@10V gate drive), lower than the TK290P60Y,RQ's 290mΩ, minimizing conduction losses for better efficiency and reduced heat generation in high-frequency switching applications.
Additionally, the VBE16R15S 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 balances drive convenience and switching reliability, seamlessly matching mainstream driver ICs without circuit adjustments.
Advanced SJ_Multi-EPI Technology, Reliability and Stability Upgraded.
The TK290P60Y,RQ relies on proven technology for low on-resistance and durability. The VBE16R15S employs advanced SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology, optimizing device reliability and switching characteristics. It undergoes rigorous avalanche testing and high-voltage screening, offering excellent single-pulse avalanche energy tolerance to handle surges during high-voltage turn-off. Through optimized capacitance design, it reduces switching losses and enhances dv/dt tolerance, ensuring stable operation under high-frequency switching and transient conditions. With an operating temperature range of -55°C to 150°C, it adapts to harsh industrial and outdoor environments. The device has passed long-term reliability tests, including high-temperature/high-humidity aging, with a failure rate below industry averages, making it ideal for critical applications like industrial control, power supplies, and motor drives.
Fully Compatible Package, Enabling Seamless Replacement.
To simplify substitution, the VBE16R15S features a TO-252 package identical to the TK290P60Y,RQ in pinout, spacing, dimensions, and thermal structure. Engineers can achieve "plug-and-play" replacement without modifying PCB layouts or thermal designs. This compatibility reduces verification time—sample validation typically completes in 1-2 days—and avoids costs from PCB revisions or retooling. It ensures unchanged product dimensions, eliminating re-certification needs and accelerating supply chain cycles for quick component upgrades.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Support.
Unlike imported components affected by logistics, trade policies, and exchange rates, VBsemi leverages China's integrated semiconductor产业链, with modern production bases in Jiangsu and Guangdong enabling full-process R&D and stable mass production. The VBE16R15S has a standard lead time within 2 weeks, with emergency orders supporting 72-hour delivery, mitigating risks from supply chain volatility and tariffs. As a local brand, VBsemi provides dedicated technical support: comprehensive documentation (substitution reports, datasheets, thermal guides, application circuits), tailored selection advice, and circuit optimization. Technical issues receive 24-hour responses for on-site or remote resolution, addressing slow support and high communication costs associated with imports.
From industrial power supplies and motor drives to lighting systems and inverters, the VBE16R15S, with its core advantages of "superior parameters, enhanced reliability, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the TK290P60Y,RQ. It is already adopted by leading companies across industries, gaining market recognition. Choosing the VBE16R15S is not just a component replacement—it is a strategic step for enterprises to upgrade supply chain security, optimize costs, and boost competitiveness, offering better performance, stable supply, and convenient support without R&D modification risks.
