Semiconductor device
 A semiconductor device includes a bipolar transistor whose emitter-collector voltage is set to satisfy a condition I.sub.BE <I.sub.CB according to a voltage applied across a base and emitter where I.sub.BE is the base current flowing through a base-emitter path in a forward direction, and I.sub.CB is the base current flowing through a collector-base path in a reverse direction.
