The Challenges for SiC Power Devices - EE Times Europe

However, silicon carbide exhibits excellent thermal resistance (meaning it can move more heat in a given time) and far fewer losses (meaning it can operate at higher temperatures). To determine how much power a SiC device can dissipate, we use a graph like the one shown on the right side of Figure 4, which gives the power density (W/mm2) for different types of devices.
