Abstract :
An optically gated, GaAs bipolar junction thyristor with a semi-insulating base layer, specifically developed for pulsed power applications, is reported, and initial device performance characteristics as a pulsed power switch are presented. The measured DC blocking voltage of the device was >600 V, peak pulsed current was >or=70 A, and the current rise rate was >1.4*10/sup 9/ A/s. These results demonstrate that GaAs based junction devices have significant potential as switching elements for pulsed power systems requiring very fast closing times.<>
