Major Japanese technology companies Rohm, Toshiba, and Mitsubishi Electric are preparing to discuss combining their power semiconductor operations. The potential merger could create the world's second-largest power chip manufacturer, trailing only Germany's Infineon.

Three major Japanese technology corporations are preparing to enter discussions about merging their power semiconductor operations in a move that could reshape the global chip industry, according to reports from the Nikkei newspaper on Thursday.

Rohm, Toshiba, and Mitsubishi Electric are expected to announce the start of these integration discussions, potentially creating what would become the globe’s second-largest power semiconductor company behind Germany’s Infineon Technologies.

The anticipated announcement could come as soon as Friday, March 26, according to the Tokyo-based financial publication. This development may also impact ongoing acquisition efforts by automotive supplier Denso, which has been pursuing a deal to purchase Rohm.

Power semiconductors are critical components used in electric vehicles, renewable energy systems, and various industrial applications, making this potential consolidation significant for the global technology supply chain.
