Abstract: With a focus on pulsed power applications, this paper presents results of the pulse current characterization of GTO thyristors developed and fabricated within a previous ISL funded project. Limited by the pulse current capability of the bonding wire connection, the devices demonstrated to handle a peak current of up to 6 kA/cm2 (about 20 µs FWHM). Pulse tests of Al wires indicate that two 50 µm wires should be sufficient to test a 1 mm2 device up to a peak current of 30 kA/cm2.
