Question

Zener diodes can be tested in the same manner as rectifier diodes provided the ohmmeter voltage is  more than the reverse voltage value of the zener.

Quizplus · Accepted Answer

Zener diodes can indeed be tested similarly to rectifier diodes using an ohmmeter, but the statement about the ohmmeter voltage needing to be more than the reverse voltage value of the Zener is incorrect. The key characteristic of Zener diodes is their ability to conduct in reverse once a certain voltage (Zener voltage) is reached, but for testing purposes with an ohmmeter, the concern is not about exceeding this voltage but rather about identifying the diode's forward and reverse bias conductivity. Exceeding the Zener voltage with an ohmmeter could potentially damage the diode.
