Zener diodes - named after its inventor Dr. Carl Zener are fundamentally used in electronic circuits for generating precise voltage references. These are devices that are able to create a practically constant voltage across them regardless of variations in circuit and voltage situations. Externally, you may find zener diodes a lot similar to standard diodes such as 1N Zener diodes also work by rectifying AC into pulsating DC quite like their traditional alternatives. However contrary to standard rectifier diodes, zener diodes are configured with their cathode directly connected with the positive of the supply, and anode with the negative supply. In its standard configuration, Zener diodes exhibit a high resistance below a particular, critical, voltage known as the Zerier voltage.


Every circuit needs a power source, but different circuits have different power requirements. For those times when you don't need a lot of power, just a precise voltage level, the simplest means of regulating the supply voltage is by using a Zener diode. In this Instructable, I will compare a typical voltage regulation circuit with the Zener diode shunt regulator circuit and show you the proper way of selecting the perfect components for your circuit needs. Correct usage of this circuit can save time and money, but it is not well suited for all designs. So grab those breadboards and let's gown to business! In case you don't know, a diode is a special type of electrical component that lets current flow freely in one direction, but blocks it from flowing in reverse - in the water analogy, the diode would be a one-way valve, only allowing water to flow in a specific direction.

By Patrick Hoppe. Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region. Click here to login. By dan. Walk through the subscriber loop and learn how the signal travels from the central office to the subscriber.

Solution: By designing the regulator here means to find the values of VZ and R. Since the load voltage is to be maintained at 12 V, we.

    Normally, it is called the V-I characteristics of a Zener diode.
