A 9.1-V zener diode exhibits its nominal voltage at a test current of 28 mA. At this current the incremental resistance is specified as 5 Ω. Find VZ0 of the Zener model.

A 9.1-V zener diode exhibits its nominal voltage at a test current of 28 mA. At this current the incremental resistance is specified as 5 Ω. Find VZ0 of the Zener model.

A. 8.96V
B. 9.03V
C. 9.17V
D. 9.24V

Correct answer is option A. 8.96. Explanation: Given us,the zener diode = 9.1 and its nominal voltage at a test current of 28 mA and incremental resistance is 5Ω

VZ = VZo + MZ IZT

9.1 = VZo + 5 `\times` 28 `\times` `10^-3`

VZo = 8.96v

VZ = VZo + 5IZ = 8.96 * 5IZ. Thus, VZ0 of the Zener model is 8.96.
