Diode rectifier characteristic. In the reverse direction, the diode rectifier will ultimately break down. The breakdown voltage is normally well in excess of the turn on voltage-the scales on the diagram have been altered (compressed) in the reverse direction to illustrate that reverse breakdown occurs.
