Enhancing Efficiency in AI Power Systems
On 21st May, Toshiba Electronic Devices & Storage Corporation commenced the shipment of test samples for its innovative 1200V trench-gate SiC MOSFET, known as the TW007D120E. This advanced device is set to enhance power supply systems in next-generation AI data centers. According to the company, the TW007D120E will also be suitable for renewable energy-related equipment.
Data centers face increasing power consumption challenges due to the rapid expansion of generative AI and the widespread use of high-power AI servers. Toshiba’s TW007D120E specifically addresses the need for improved power conversion efficiency and higher power density in these environments. The growing deployment of 800V high-voltage direct current (HVDC) architectures further underscores this demand.
Featuring a proprietary trench-gate structure developed by Toshiba, the SiC MOSFET achieves a remarkable 58% reduction in On-resistance per unit area compared to previous models. This technology effectively minimises conduction and switching losses, thereby boosting overall system efficiency. Toshiba reports that the figure of merit, On-resistance × gate-drain charge, is improved by approximately 52%.
Innovative Cooling Solutions
Housed in a QDPAK package, the TW007D120E supports top-side cooling. This design not only enhances power density but also improves thermal performance, which are critical for efficient power conversion in AI data centers. As a result, the device contributes to reduced heat generation and increased operational efficiency.
Mass production of the TW007D120E is slated for the fiscal year 2026. Toshiba is also exploring the use of this technology in automotive applications as part of its commitment to supporting decarbonization efforts across various industrial sectors. The development of this MOSFET is based on results from JPNP21029, a project subsidised by the New Energy and Industrial Technology Development Organisation (NEDO).
The MOSFET’s development underscores Toshiba’s dedication to advancing energy-efficient technologies and reducing CO₂ emissions in data centers worldwide. By 2026, the company plans to expand its lineup further, contributing to the realization of a decarbonized society.
With the TW007D120E, Toshiba aims to contribute significantly to the miniaturization and improved efficiency of power supply systems. This innovation aligns with the global push towards a more sustainable and energy-efficient future, supporting the next-generation AI data centers and industrial equipment.
