Superjunctions, the power-semiconductor intelligence layer
An engineering-focused guide to superjunction power semiconductors, their devices, materials, applications, companies, research, and first-order design calculations.
Field notes
Superjunctions.com links semiconductor structures to the equipment that uses them, organizing the subject around device physics, manufacturer resources, application contexts, research, and first-order calculations. Its stated coverage spans 600V–1700V+ voltage classes and follows the RDS(on) × Qg trade-off, while the application map reaches from PFC and onboard charging to solar conversion, UPS, telecom, and data centers. The homepage also identifies a research item on polarization-engineered III-nitride structures and names tools for loss, thermal, figure-of-merit, and voltage-margin estimates.
