The SiC device market will reach $8.2B in 2028, according to Yole Intelligence’s Power SiC / GaN Compound Semiconductor Market Monitor.

The SiC ecosystem has been reshaped by the major SiC market players in recent years. Every manufacturer has its own solutions for die design and packaging integration. This leads to strong competition, which will accelerate technical innovation and lower prices.
Although some SiC business models are different, some trends are emerging, such as vertical integration in order to maximize revenues in the near future. This restructuring we are seeing of the supply chain is driven by the main cost factors.
Since the commercialization of the first SiC device in 2001, the performance and value that these devices add has steadily been proven. Device price has also become increasingly acceptable to end-users.

In this report, Yole SystemPlus presents an overview of the state-of-the-art of discrete SiC diodes, with a detailed analysis of 21 diodes. We cover all the main available voltage classes: 650V, 1200V, 1700V, and 3300V. This report also furnishes an exhaustive overview of the worldwide players: Infineon, Wolfspeed, Rohm, STMicroelectronics, onsemi, UnitedSiC (Qorvo), GeneSiC (Navitas), WeEn Semiconductors, Inventchip, Panjit, Comchip, Microchip, Littelfuse, and SemiQ.
Compared to our 2020 report, there are 10 new devices from eight players, including seven new players: WeEn Semiconductors, Panjit, Inventchip, Comchip, GeneSiC (Navitas), Littelfuse, and SemiQ.
This report provides optical and scanning electron microscope (SEM) pictures from the device’s opened package, down to the microscopic level of diode design – with a focus on the latter. This physical analysis is shown for the 10 newly added diodes (for diodes previously analyzed by Yole SystemPlus, please refer to the 2020 report for a full physical analysis). Moreover, the physical and technological parameters of all 21 SiC diodes are detailed in an Excel file.

Yole SystemPlus has performed cost simulations for the 10 newly-added diodes. We break down their estimated manufacturing costs and selling prices.
Lastly, this report provides exhaustive physical, technology, and manufacturing cost comparisons of the analyzed devices.
