Transphorm
Transphorm's Overview
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.
