Abstract:
1. A junction-gate type static induction thyristor for use in a high-voltage pulse generator which uses an inductive element, a path from an anode to a cathode of said junction-gate type static induction thyristor being connected to said inductive element in series, said junction-gate type static induction thyristor comprising: a p-emitter region connected to said anode; an n-buffer region provided on said p-emitter region; an n-base region provided on said n-buffer region; a p-base region buried in said n-base region and connected to a gate of said junction-gate type static induction thyristor; and an n-emitter region provided on said n-base region and connected to said cathode, wherein a voltage of a high-voltage pulse generated by said high-voltage pulse generator saturates at no more than a saturation voltage when electric energy supplied from a power supply is increased with an increase in energy of said high-voltage pulse, said saturation voltage being not more than an anode-cathode forward breakdown voltage obtained when a gate-cathode circuit of said junction-gate type static induction thyristor is shorted.
