ABSTRACT:
A first rectifying contact portion of a semiconductor device such as a Zener diode has a small area in order to attain a hard breakdown characteristic and a low noise characteristic. When a predetermined current which is not greater than the maximum allowable instantaneous value of non-D.C. currents flows through the first rectifying contact portion, a second rectifying contact portion which has a large area starts breakdown due to a voltage drop across a resistance component connected in series with the first rectifying contact portion and a breakdown voltage of the first rectifying contact portion.
Owing to the fact that current is dispersed to the first rectifying contact portion and the second rectifying contact portion, a semiconductor device such as a Zener diode exhibiting a high endurance characteristic against surge voltages can be provided.
