Testing was conducted to determine the performance of new Silicon Carbide (SiC) Super Junction Transistors (SJTs) in pulsed operation. These devices, developed at GeniSiC Semiconductor, are quasi-majority carrier devices. They were first characterized using an Agilent B1505A Power Device Analyzer to determine their operational characteristics. The devices were then pulsed using a high current test apparatus developed at Texas Tech University. After single shot measurements were taken the devices were pulsed at rep-rates of 1 Hz, 5 Hz, and 10 Hz for a total of 3000 pulses. These devices were then placed back on the curve tracer to determine if the pulse testing had any permanent effects on the device.
