Assessing Short-Circuit Robustness of 1200 V SiC MOSFETs: Using Deep Structural and Physical Analysis

Silicon carbide (SiC) transistors are known for their high breakdown voltage capabilities and ability to operate at much higher temperatures relative to silicon (Si) power semiconductors. The first commercial SiC MOSFETs were introduced in 2010 [1], [2]. Currently, third generation devices are in production and leading manufacturers will soon release fourth generation products [3]. However, usage of these devices requires special considerations. Due to its impact in circuit design and device reliability, short-circuit (SC) robustness is of prime importance among them.
