摘要：
A semiconductor switching device of field-drive type includes a bipolar component having a pnp transistor portion (8) and a npn transistor portion (9), said pnp transistor portion (8) and said npn transistor portion (9) being connected to cause a positive feedback, and a n-channel MOS transistor (11) connected across an emitter electrode (n3) and a collector electrode (n2) of said npn transistor portion (9), wherein a p-channel MOS transistor (10) is connected across an emitter electrode (p1) and a connector electrode (p2) of the pnp transistor portion (8), and a control terminal of said n-channel MOS transistor (11) is electrically connected with a control terminal of said p-channel MOS transistor (10). Said device is operable to control the main drive section even in the floating state and to drive the main drive section by a small control current.
