SiC MOSFET(1200V):Three U.S. Companies (AOS,Vishay,MCC) Overview and Comparative Analysis Report

Report Overview

The SiC power device market is projected to see continuous growth, driven by the expanding EV market as well as increasing adoption in industrial equipment, renewable energy, power infrastructure, and AI data centers.
While major U.S. SiC manufacturers include Wolfspeed, onsemi, and Navitas Semiconductor (GeneSiC), other manufacturers have also been strengthening their development and product deployment of SiC power devices in recent years. Therefore, understanding each company’s technical capabilities and device structures has become increasingly important.
In this newly released report, we focus on three highly anticipated companies following the major U.S. SiC manufacturers, analyzing their product and technical overviews. Furthermore, we evaluate the actual performance of the devices and compare their structures—including RonA, cell structure, and cell pitch—to clarify the characteristics and positioning of each company’s SiC MOSFET technology.

Analysis result summary

Overview and Comparative Analysis Report (32 pages)
- The specific on-resistance per transistor area (RonA) for the three products evaluated in　this report is presented in a trend table to clarify the market positioning of each manufacturer(see P. 3).Furthermore, by comparing the datasheet values per chip size with those of products from major manufacturers, we confirmed that the switching loss value of the AOS product has specific characteristics.
- The report includes cross-sectional analysis of the cell structures for the three products, comparing parameters such as cell pitch and epitaxial layer thickness.

It also outlines technical concerns and key characteristics identified during the analysis.

Note: Detailed structural analysis reports for each product (Alpha and Omega Semiconductor,Vishay, and MCC) are currently under planning. Please contact us for details.
