Partial specifications of a collection of zener diodes are provided below. For each, identify the missing parameter and estimate its value. Note from Fig. 4.19 that VZK VZ0 and IZKis very small.
(a) VZ= 10.0 V, VZK= 9.6 V, and IZT= 50 mA
(b) IZT= 10 mA, VZ= 9.1 V, and rz= 30O
(c) rz= 2O, VZ= 6.8 V, and VZK= 6.6 V
(d) VZ= 18 V, IZT= 5 mA, and VZK= 17.6 V
(e) IZT= 200 mA, VZ= 7.5 V, and rz= 1.5O
Assuming that the power rating of a breakdown diode is established at about twice the specified zener current (IZT),
what is the power rating of each of the diodes described above?
