Move made to expand its power portfolio with GaN technology
A subsidiary of Renesas Electronics Corp., supplier of advanced semiconductor solutions, has entered into a definitive agreement to acquire all outstanding shares of Transphorm Inc., global provider of robust gallium nitride (GaN) power semiconductors,
The deal 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 (WBG) materials, represented by silicon carbide (SiC) 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% 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.
“Transphorm is a company uniquely led by a seasoned team rooted in GaN power and with origins from the University of California at Santa Barbara,” said Renesas CEO Hidetoshi Shibata. “The addition of Transphorm’s GaN technology builds on our momentum in IGBT and SiC. It will fuel and expand our power portfolio as a key pillar of growth, offering our customers the full ability to choose their optimal power solutions.”
