In high-efficiency DC-DC converters, switching regulators, and various power management applications, TOSHIBA's TPH9R00CQH,LQ, with its high-speed switching capability, low gate charge, low output charge, and low on-resistance, has long been a key component for engineers worldwide. However, amid global supply chain uncertainties, trade tensions, and post-pandemic logistics challenges, this imported MOSFET increasingly reveals pain points: extended lead times, cost volatility due to exchange rates, and delayed technical support, which hinder production schedules and cost optimization for downstream enterprises. Consequently, domestic substitution has evolved from an option to a necessity, crucial for ensuring supply chain security, reducing costs, and enhancing competitiveness.
Leveraging its deep expertise in power semiconductors, VBsemi introduces the VBGQA1151N N-channel power MOSFET through independent R&D. This product is meticulously designed to替代 the TPH9R00CQH,LQ, offering core advantages of parameter enhancements, technological parity, and full package compatibility. It serves as a drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for high-efficiency electronic systems.
Comprehensive Parameter Optimization, Enhanced Performance, Adapting to Demanding Applications.
Tailored as a domestic alternative to the TPH9R00CQH,LQ, the VBGQA1151N achieves significant improvements in key electrical parameters, ensuring robust performance for high-current applications:
Firstly, the drain-source voltage remains 150V, matching the original model, providing reliable operation in standard voltage environments. Secondly, the continuous drain current is boosted to 70A, surpassing the original 64A—a 9.4% increase in current-carrying capacity, enabling support for higher power densities and improved stability in demanding circuits. Thirdly, the on-state resistance is 13.5mΩ (@10V gate drive), optimized alongside advanced SGT technology to balance conduction losses with switching efficiency. Although slightly higher than the original 7.3mΩ, this is compensated by superior switching characteristics, reducing overall system losses in high-frequency operations. Additionally, the VBGQA1151N features a lower gate threshold voltage of 3V (compared to 3.3-4.3V), ensuring easier drive compatibility and enhanced noise immunity, with a gate-source voltage rating of ±20V for robust ESD protection. These upgrades collectively offer ample performance headroom for efficient DC-DC conversion and switching regulator designs.
Advanced SGT Technology, Elevating Reliability and Switching Performance.
The TPH9R00CQH,LQ excels in high-speed switching with low gate and output charge. The VBGQA1151N employs state-of-the-art Shielded Gate Trench (SGT) technology, inheriting and enhancing these traits. SGT design minimizes gate charge (Qg) and output charge (Qoss), significantly reducing switching losses and improving efficiency in high-frequency applications. The device undergoes rigorous avalanche testing and high-voltage screening, ensuring excellent durability against transient surges. Its optimized internal capacitance structure enhances dv/dt tolerance, enabling stable operation under fast transients and high-frequency switching, directly matching the TPH9R00CQH,LQ's scenarios without circuit changes. With an operating temperature range of -55°C to 150°C and validation through extended reliability tests, the VBGQA1151N demonstrates low failure rates, ideal for critical applications like industrial power systems, automotive electronics, and renewable energy converters.
Fully Compatible Package, Enabling Seamless and Immediate Replacement.
To simplify domestic substitution, the VBGQA1151N addresses integration concerns through package design. It utilizes a DFN8(5X6) package, fully compatible with the TPH9R00CQH,LQ in pinout, dimensions, and thermal footprint. Engineers can directly replace the original component without PCB layout changes or thermal system adjustments, achieving "plug-and-play" convenience. This compatibility slashes verification time—sample testing typically completes within 1-2 days—and avoids costs from redesigns, mold modifications, or re-certification. By streamlining the replacement process, it helps enterprises quickly adopt domestic solutions and capitalize on market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Technical Support.
