Product Description:
Sic Silicon Carbide Wafer 5*5mm/10*10mm 4H-P Type Production Grade For Power Electronics
4H-P silicon carbide (SiC) is an important semiconductor material commonly used in high-temperature, high-frequency, and high-power electronic devices. 4H-SiC is a type of its crystal structure that has a hexagonal lattice structure. The wide bandgap (approx. 3.26 eV) allows it to operate in high temperature and high voltage environments. High thermal conductivity (about 4.9 W/m ·· K), superior to silicon, can effectively guide and dissipate heat. P-type doped silicon carbide has a low resistivity and is suitable for the construction of PN junctions. With the development of electric vehicles and renewable energy technologies, the demand for 4H-P type silicon carbide is expected to continue to grow, driving related research and technological advancements.
