Zener Diode As Voltage Regulator Experiment Circuit Diagram. The output voltage is always selected with a breakdown voltage vz of the diode. Choose the zener diode to start the experiment.
The zener diode can work as a voltage regulator if it is introduced in a circuit. It is driven by a current source. Note down the corresponding input voltage and output voltage and tabulate it.
The zener diodes have a voltage rating equivalent to the intended output voltage that may be closely match the desired output value.
The circuit diagram of a voltage regulator using a zener diode is shown. The zener diodes have a voltage rating equivalent to the intended output voltage that may be closely match the desired output value. Incremental resistance rz 20ω nominal voltage vz 7 1v measured at a test current of 20ma the zener diode requires a current equal to or greater than iz min 2 5ma to operate correctly. The output across the diode will be constant.
