Silicon Carbide SiC
Wide-bandgap semiconductor (3.3 eV) — perfect for high-voltage high-temperature power electronics. Drives EVs (Tesla, BYD), solar inverters, EV chargers.
Tesla Model 3 (2017) was the first EV with a SiC inverter — increased range 5-10 % vs IGBT. Wolfspeed (ex-Cree) is the leading wafer maker, deeply in debt 2024. Competitor: GaN below 1200V, traditional Si IGBT for cost-sensitive. Manufacturers: Infineon, ST Microelectronics, onsemi.
