Unlike an IGBT, the fault on a SiC device may have to be detected before the short-circuit current reaches a peak. A destructive test can be performed to test this feature, such as the example test shown in Figure 8. This test involved an ADuM4177 gate driver and CAB450M12XM3 SiC module (rated for 1,200 V/450 A). The fault was detected …

However, the blocking voltage capability of a SiC MOSFET will reduce with temperature. Taking as an example a 1200 V 20 m SiC MOSFET power module, the typical derating in the blocking voltage (VDS) at −40°C is around 11% compared to the value at 25°C. Even if onsemi devices have typically some margin, the derating in the VDS should be

The results are highest efficiency, higher switching frequencies, less heat dissipation, and space savings – benefits that, in turn, also reduce the overall system cost. We identified this potential almost 30 years ago and established a team of experts in 1992 to develop SiC diodes and transistors for high-power industrial applications.
