Transphorm, Inc. is a global semiconductor company that designs, manufactures, and sells high-performance, high-reliability Gallium Nitride (GaN) power conversion devices. Their GaN FETs (Field-Effect Transistors) are engineered to offer superior efficiency, power density, and thermal performance compared to traditional silicon-based power transistors. This enables smaller, lighter, and more efficient power supplies, adapters, inverters, and other power conversion systems. Transphorm's products target a wide range of markets, including data centers, renewables, industrial power, automotive (EVs), and consumer electronics. They are known for their vertically integrated approach, robust JEDEC and AEC-Q101 qualified GaN platforms. In early 2024, it was announced that Renesas Electronics Corporation would acquire Transphorm, a transaction completed in May/June 2024, aiming to expand Renesas's power portfolio with Transphorm's GaN expertise.
Serves as the primary center for research and development, engineering, corporate leadership, sales, and marketing operations for its GaN semiconductor business.
Located in a technology-rich area often referred to as the 'Santa Barbara Tech Coast.' The facility likely includes advanced semiconductor design labs, testing equipment, and engineering offices.
Fosters innovation, collaboration, and engineering excellence, typical of a cutting-edge semiconductor company. Emphasis on developing advanced GaN technology and solving complex power efficiency challenges.
Central hub for Transphorm's strategic decision-making, product innovation, and global operations coordination before its acquisition by Renesas.
Prior to its acquisition by Renesas, Transphorm operated with a global footprint, supporting customers worldwide through direct sales, field application engineers (FAEs), and a network of distribution partners across North America, Europe, and Asia. Key functions supported globally included sales operations, technical customer support, application-specific engineering, and logistics for its advanced GaN semiconductor products. Its manufacturing and R&D collaborations also extended internationally, particularly in Japan.
