ROHM Semiconductor

ROHM Co., Ltd. is a Kyoto-headquartered electronic-component manufacturer established in 1958. The company began with resistors and subsequently expanded across integrated circuits, discrete semiconductors, optoelectronics, passive components and modules, giving it one of the broader product ranges among Japanese component manufacturers.

ROHM's IC portfolio includes memory, amplifiers and linear devices, power management, clocks and timers, logic, data converters, sensors and MEMS, display drivers, motor and actuator drivers, interfaces, wireless LSIs, audio and video devices, and microcontrollers. Its discrete range includes MOSFETs, bipolar transistors, diodes, IGBTs, intelligent power modules and wide-bandgap power devices based on silicon carbide and gallium nitride. ROHM also manufactures LEDs, laser diodes, optical sensors, resistors, capacitors and subsystem modules.

Power semiconductors and analog ICs are key strategic areas for the company, with SiC devices particularly important in EV traction, charging, industrial power conversion and renewable-energy systems. This combination of power devices, control ICs and supporting passives makes ROHM a useful manufacturer for engineers building complete power and motion-control subsystems.
