Rohm and Toshiba in talks about merging their power semi units


Monday, March 16, 2026

Rohm and Toshiba are in talks to merge their power semiconductor businesses, reports the Nikkei.

The report comes after last week’s news that Denso is proposing to take over Rohm.

Toshiba and Rohm each have about 2.5% market share in power semis, which is a business under threat from low-cost Chinese competition.

It is thought that Rohm and Toshiba may form a Toshiba TKxxxZ60Z1 power mosfetsseparate joint venture for their power semi units or, possibly, Denso may take over Rohm plus the Toshiba power semi business.

Rohm invested about $2bn in Toshiba in 2023 through the investment fund Japan Industrial Partners, when Toshiba was restructuring.
