The 5SGA30J4502 from ABB is an Asymmetric Gate Turn-Off Thyristor that has been designed to withstand the effects of cosmic radiation in harsh environments. This thyristor has a break-over voltage of up to 4500 V and a break-over current of less than 3 kA. It has a gate trigger voltage of 1 V and a gate trigger current of 3 A. This asymmetric thyristor is based on a patented free-floating Silicon technology that offers low on-state and switching losses. It is available in an industry-standard disc package that measures 105.6 x 26 mm.
