ROHM Semiconductor, established in Kyoto, Japan in 1958, has evolved from a small resistor manufacturer into a global leader in semiconductor technology. Starting with resistors, ROHM expanded into transistors and diodes in 1967, and ICs in 1969, building a comprehensive portfolio of electronic components.
ROHM's extensive product lineup includes:
- SiC (Silicon Carbide) power devices under the EcoSiC brand
- IGBTs, SJ MOSFETs, and power transistors
- Schottky barrier diodes and power diodes
- GaN HEMTs (High Electron Mobility Transistors)
- Power management ICs, regulators, and gate drivers
- LEDs, optical sensors, and resistors
ROHM's EcoSiC brand represents their leadership in silicon carbide power semiconductors, offering superior voltage and temperature tolerance compared to silicon. These SiC devices are ideal for high-power applications such as electric vehicles, solar inverters, and uninterruptible power supplies (UPS), delivering improved efficiency and reduced system size.
