    Is ROHM (TSE:6963) Quietly Reshaping Its AI Power Niche With New 600V MOSFET Lineup?

    Simply Wall St·07/10/2026 14:34:37
    Listen to the news
    • ROHM Semiconductor recently launched a new lineup of 600V Super Junction MOSFETs, the R60xxXNx and PrestoMOS R60xxWNx series, now in mass production and aimed at high-efficiency, space-saving power supplies for AI servers, data centers, and industrial equipment.
    • The addition of compact DFN8080-5L and TOLL surface-mount packages with common footprints could make ROHM’s devices easier drop-in options for power designers seeking multi-sourcing flexibility and improved thermal performance.
    • We’ll now examine how this expansion into high-efficiency 600V Super Junction MOSFETs, particularly for AI server power supplies, may influence ROHM’s investment narrative.

    ROHM Investment Narrative Recap

    To own ROHM, you need to believe that its focus on power devices across AI servers, automotive and industrial markets can translate into a return to sustainable profitability from recent losses. The new 600V Super Junction MOSFETs look directionally supportive of near term catalysts in AI server and industrial power, but do not meaningfully reduce key risks around weak industrial demand, negative operating profit and execution on cost reductions.

    Among recent announcements, the June 10 launch of ROHM’s 1,200V SiC MOSFET in the new TSC3PAK package for xEV onboard chargers stands out. Together with the new 600V Super Junction MOSFET lineup for AI servers and industrial equipment, it reinforces ROHM’s emphasis on higher value power solutions in automotive and data center, which are central to the company’s longer term growth and margin improvement ambitions despite the current earnings pressure.

    Yet, while products for AI servers and xEVs are encouraging, investors should also be aware that...
