Abstract
Certain applications require devices that can switch high peak current with fast rise times and narrow pulse width. This work was done as an initial study to investigate the performance of Silicon Carbide (SiC) Gate turn-off thyristor (GTO) in these applications. The SiC GTOs were designed for high turn-off gain and not optimized for pulse applications. The GTOs were tested as discharge switches in a low inductance circuit delivering 2/spl mu/s pulses with a maximum switching current of 1.4 kA (94.6 kA/cm/sup 2/) and a current rise time of 2.4 kA//spl mu/s. All the devices were switched until failure. The failure modes will be discussed.
