The transaction values ​​Transphorm at approximately $339 million. The acquisition will provide Renesas with proprietary GaN technology, a key next-generation material for power semiconductors, expanding its reach in fast-growing markets such as electric vehicles, computing (data centers, AI, infrastructure), renewable energy, industrial power conversion, and fast chargers/adapters.

Demand for highly efficient power systems is increasing as a fundamental element for carbon neutrality. To address this trend, an industry-wide transition to wideband bandwidth (WBG) materials, exemplified by silicon carbide (SiC), is also underway. These advanced materials enable a wider range of switching voltages and frequencies than conventional silicon-based devices. To capitalize on this momentum, Renesas has announced the establishment of its own SiC production line, supported by a 10-year SiC wafer supply agreement.

Renesas now aims to further expand its WBG portfolio with Transphorm's expertise in GaN, an emerging material that enables higher switching frequencies, lower power losses, and smaller form factors. These advantages enhance customer systems with greater efficiency, a smaller and lighter composition, and a lower overall cost. As a result, demand for GaN is projected to grow by more than 50% annually, according to an industry study. Renesas will implement Transphorm's self-qualified GaN technology to develop new enhanced power solution offerings, such as X-in-1 powertrain solutions for electric vehicles, along with computing, energy, industrial, and consumer applications.
