SiC devices

Silicon Carbide (SiC) devices, favored for their low ON resistance and superior performance in high-temperature, high-frequency, and high-voltage settings compared to silicon, are the leading choice for next-gen, low-loss semiconductors because the tech permits simplified designs with fewer components, reducing overall complexity.

SiC’s low ON resistance also leads to substantially lower energy consumption, facilitating the creation of eco-friendly products and systems that contribute to reduced CO2 emissions.

Infineon is adopting a multi-source strategy to secure access to high-quality 150mm and 200mm SiC wafers — The prolonged partnership with Wolfspeed is expected to strengthen Infineon’s supply chain resilience, ensuring a stable supply base for the coming years.

Jochen Hanebeck, CEO of Infineon Technologies, stated that the demand for silicon carbide devices is increasing, and the multi-source strategy aims to secure access to a global, high-quality, and long-term supply base for SiC wafers. This is crucial for supporting the growing markets in automotive, industrial, and energy sectors, where silicon carbide solutions are gaining popularity due to their ability to enable smaller, lighter, and more cost-effective designs.
