Abstract:
Apparatus and methods are disclosed, such as those involving protection of a semiconductor junction of a semiconductor device. One such apparatus includes a bipolar transistor including an emitter, a base, and a collector; a first junction protection device including a first end electrically coupled to the emitter of the bipolar transistor, and a second end electrically coupled to a node; and a second junction protection device including a first end electrically coupled to a voltage reference, and a second electrically coupled to the emitter of the bipolar transistor. Each of the first and second junction protection devices may have a substantially higher leakage current than the leakage current of the base-emitter junction of the bipolar transistor when reverse biased.
