The i -v characteristic of a semiconductor diode designed to operate in the Zener breakdown region is shown in Figure P9.52. The Zener or breakdown region extends from a minimum current at the knee of the curve, equal here to about ?5 mA (from the graph), and the maximum rated current equal to ?90 mA (from the specification sheet). Determine the Zener resistance and Zener voltage of the diode.
