The STC30N120 is the first generation 1200V SiC MOSFET device from STMicroelectronics. The device has a planar structure and a design that allows good electrical performance, such as high current density. Moreover, the supply chain and manufacturing choices lead to a very competitive cost. The device is suitable for high power applications like motor drives, inverters, DC-DC converters and power supplies.

The STC30N120 integrates first generation high-voltage SiC power MOSFET dies in a dedicated discrete package.

The device is assumed to operate at very high temperature, up to 200°C, and to have an on-resistance of 90mΩ, with generally standard SiC manufacturing technology.

The report goes into depth in its analysis of the packaging and the components, with images of the complex planar SiC structure.

It also includes production cost analysis and detailed comparison with Rohm and Wolfspeed’s SiC MOSFETs and with 1200V silicon IGBTs. The comparison highlights differences in the electrical parameters, supply chain and production cost.
