Top SiC Semiconductor Companies for High-Efficiency Power Solutions

Losing 20% energy in power conversion? Overheating systems cutting your product lifespan? You're not alone. Legacy silicon semiconductors hit physical limits at 150°C—while silicon carbide (SiC) handles 200°C+ like a pro. The math is brutal: 70% of industrial motor failures trace to thermal stress. That's why manufacturers race to adopt SiC.
