In this illustration we will going to build a Zener Diode Regulator. A Zener diode is important device for regulating voltage by connecting on the right way in the circuit, it can act as a voltage regulator to regulate the voltage feeds to your device.

To connect a zener diode is a circuit and provide a voltage regulation, the zener diode should be connected in reverse biased, in parallel on the power source which gives the zener diode it s voltage, along the source connected to a resistor.

Required Component

1x 5.1v Zener Diode

The 9v power supply drops across the resistor and the zener diode. This particular zener diode in use has a breakdown voltage of 5.1v This means that the zener diode will have a voltage drop on 5.1v while the remaining 4v falls across the Resistor. The zener diode will maintain a steady, constant voltage of 5.1v.

If you don’t have an exact values above such as DC voltage or the exact zener diode, experiment with other components, you just have to make sure that you have a voltage that is higher than the breakdown voltage of the zener diode, you can use your digital tester to measure the exact power breakdown at the voltage output.
