Diode Characteristics

The graph below shows the current/voltage characteristics of a typical silicon diode. The reverse leakage current has been exaggerated to make it show on the graph. The forward voltage is about 0.7 volts. The reverse breakdown voltage varies between different diode types. The range of breakdown values goes from a few Volts to over 1000 Volts.
