- ROHM Co., Ltd. is a Japanese manufacturer specializing in the design and production of semiconductors and electronic components. It offers a diverse product portfolio that includes integrated circuits such as analog ICs, power management ICs, and motor drivers; discrete semiconductor devices including diodes, transistors, MOSFETs, and silicon carbide (SiC) power devices; and other electronic components. ROHM serves multiple markets including consumer electronics, automotive, industrial equipment, and communication infrastructure. Founded in 1958 and headquartered in Kyoto, Japan, ROHM operates globally through a network of development, manufacturing, and sales offices. In recent years, ROHM has strategically expanded its power semiconductor lineup, notably with its EcoSiC brand launched in 2024 for silicon carbide power products, complementing its EcoGaN portfolio of gallium nitride (GaN) devices introduced earlier. The company has also developed advanced products such as 650V GaN HEMTs in compact TOLL packages to support applications requiring high efficiency and miniaturization. ROHM has entered a significant strategic partnership with Taiwan Semiconductor Manufacturing Company Limited (TSMC) announced in late 2024, collaborating on the development and volume production of automotive-grade GaN technology. Additionally, ROHM commenced mass production of SiC MOSFETs in advanced TOLL packages in 2025 to meet growing demand in industrial equipment and energy storage markets. ROHM integrates its semiconductor manufacturing vertically, handling wafer fabrication through to packaging in-house, with notable collaborations with external partners like ATX to enhance GaN device production capabilities. The company reported consolidated net sales of ¥448.5 billion for the fiscal year ending March 2025 and continues to emphasize innovation in power management, automotive electronics, and energy-efficient solutions. ROHM's subsidiaries include Wako Electric and Apollo Electronics, supporting its comprehensive product and service offerings worldwide.
