Product Description
Sic Silicon Carbide Semiconductor Devices Multiple Crystal Forms 4H 6H 3C Custom Size 5G Communication Chips
A silicon carbide chip is a semiconductor device made of silicon carbide (SiC) material. It takes advantage of the excellent physical and chemical properties of silicon carbide to exhibit excellent performance in high-temperature, high-pressure and high-frequency environments.
Features
• High hardness and wear resistance: Silicon carbide has high hardness and excellent wear resistance, which can resist surface wear and extend service life.
• High strength: Able to withstand high loads and high mechanical stress, suitable for use in high load and high strain environments.
• High thermal stability: Silicon carbide has excellent thermal stability, small coefficient of thermal expansion, high thermal conductivity, can withstand stress and thermal shock at high temperatures, and the ultimate working temperature can reach more than 600°C.
• Wide bandgap bandgap: SiC's wide bandgap allows it to perform well in high-temperature and high-voltage environments, making it suitable for high-power and high-temperature applications.
• High electron mobility: The high electron mobility allows the device to operate at high speeds and at high frequencies.
• High electron saturation rate: The electron saturation rate of silicon carbide is twice that of silicon, allowing silicon carbide devices to achieve higher operating frequencies and higher power densities.
• High breakdown electric field strength: Able to withstand high voltage operation, reducing size and weight.
• Chemical Stability: Extremely resistant to most acids, alkalis and oxidizing agents, and retains performance in harsh chemical environments.
