摘要
The short circuit (SC-SOA) capability of power devices is crucial for power systems. In this paper, 1.2 kV SiC MOSFETs and JBSFETs are characterized, and their SC-SOA behavior was tested and analyzed. Due to the lower saturated drain current, the JBSFETs were found to have superior SC-SOA compared with MOSFETs despite the integrated Schottky contact. A new short circuit failure mechanism related to melting of the top Al metallization is proposed based up on nonisothermal TCAD numerical simulations supported with SEM measurements of failed die using Energy Dispersive X-ray Spectroscopy (EDS) analysis.
