<p>A thyristor, suitable for electrical switching in automotve applications, having two gates, one (42) for turn-on and one (44) for turn-off, without requiring change of anode or cathode potentials, comprises a semiconductor body (24) having successive contiguous P, N, P, N-type regions (30, 28, 24 ,22), and a portion (24b) of the second P-type region (24) having a surrounding N-type region (26) producing a current flow pinch effect. </p> |
