Describe the proper setup and conduct of a zener diode regulation test.

What will be an ideal response?


The output of the power supply is connected with a limiting resistor in series with a zener diode to be tested. A voltmeter is connected across the zener diode under test to monitor the zener voltage. The output voltage is slowly increased until the specified current is flowing through the zener diode. The current is then varied on either side of the specified zener current (IZ). If the voltage remains constant, the zener diode is operating properly.
