Renesas Electronics Corporation and Transphorm, Inc. today announced that they have entered into a definitive agreement pursuant to which a subsidiary of Renesas will acquire the GaN . The acquisition will provide Renesas with in-house GaN technology, a key next-generation material for power semiconductors, expanding its reach into fast-growing markets such as EVs, computing (data centers, AI, infrastructure), renewable energy, industrial power conversion and fast chargers/adapters.
Demand for highly efficient power systems is increasing as building blocks for carbon neutrality. To address this trend, an industry-wide transition toward wide bandgap materials, represented by silicon carbide and GaN, is also being seen. These advanced materials allow a broader range of voltage and switching frequency than conventional silicon-based devices. To build on this momentum, Renesas has announced the establishment of an in-house 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 frequency, lower power losses, and smaller form factors. These benefits empower customers’ systems with greater efficiency, smaller and lighter composition, and lower overall cost. As such, demand for GaN is predicted to grow by more than 50 percent annually, according to an industry study. Renesas will implement Transphorm’s auto-qualified GaN technology to develop new enhanced power solution offerings, such as X-in-1 powertrain solutions for EVs, along with computing, energy, industrial and consumer applications.
