The silicon carbide (SiC) device market is estimated to be rising at a compound annual growth rate (CAGR) of 30%, from $225m in 2019 to more than $2. Because SiC is the third-hardest composite material in the world and is also very fragile, its production poses complex challenges related to cycle time, cost, and dicing performance. For the future, EPC has plans to go to 900V, which would require a vertical device structure. As a unipolar power device, due to its advantages such as low on-resistance, high input impedance, and high switching speed, SiC MOSFET will become an ideal high-voltage power switching device within the blocking voltage range of 300–4500 V, and it is entirely possible to replace Si IGBT devices further improve the overall. For this reason, GaN technology tends to present an advantage in high-frequency operations. This material and its resulting products are also causing some stir in the market at the moment, but at the moment the market traction is not as big as it is for SiC and the focus is more on devices around and below 600V in high frequency applications. Wolfspeed's industry leading SiC MOSFETs replace traditional silicon-based solutions with Silicon Carbide to reduce system size, weight, complexity, & cost. Sic Discrete Device 6. Despite being a relative latecomer to the power SiC device market, onsemi’s 2023 Q1 results suggest it is on track to achieve ambitious revenues of $1 billion in 2023.
