Title: Self-arc-extinction type thyristor
Inventor: HASHIMOTO OSAMU
IPC: H01L29/74
Filed: 1988-06-01
Abstract: PURPOSE:To stabilize the current interrupting wave form by a method wherein a flexible part made of multiple fine wires is laid between gate lead rigid body parts so that any electromagnetic oscillation in said part exerted by a large current in time of turn off may not be propagated to the coupling part of said part with a gate terminal by caulking process. CONSTITUTION:Within a gate lead 7, the rigid body part 71 from one end in contact with a gate electrode 12 of a thyristor main body 1 by the force of a spring member 6 as well as the other rigid body part 72 to the other end caulked with a terminal 8 respectively made of one conductor are connected to each other by a flexible part 73 made of multiple fine conductors in the intermediate part. Consequently, any oscillation in said gate lead part 71 near the gate electrode 12 due to powerful electromagnetic force exerted in time of turn off can be buffered by the flexible part 73 so that the oscillation may not be propagated to the coupling part of said gate lead part 72 with the gate terminal 8 by caulking process. Through these procedures, the coupling part can be prevented from loosening due to repeated propagation of the oscillation enabling the stable connection to be maintained.
