Wolfspeed (a Cree Company) has proposed the first 900V SiC MOSFET device. The device is a planar MOSFET with lower Rdson, smaller size, and higher current density respective to Cree’s previous-generation SiC MOSFET.
The SiC C3M™ Platform is the first 900V SiC MOSFET platform, designed by Wolfspeed for high-power applications like renewable energy, DC/DC converters, and telecom power supplies. Compared with previous-generation SiC MOSFETs, this third generation allows for a smaller device, higher current density, and lower on-resistance for the same current. The SiC C3M™ Platform proposes devices competitive with the latest SJ MOSFETs and GaN HEMT in terms of cost and performance.
The SiC C3M™ Platform includes three devices at different currents, assembled in two packages. This report presents a deep analysis of the C3M0280090 device and an overview of C3M0120090D and C3M0065090D assembled in a TO220 package. Moreover, this report studies the potential evolution of the device’s cost over the next five years according to technology and market trends.
Also included is a comparison with previous Cree SiC MOSFET generations and a cost comparison with Infineon’s Si SJ MOSFET and GaN Systems’ GaN HEMT.
