However, when connected in the reverse mode, which is usual in most of its applications , a small leakage current may flow. As the reverse voltage increases to the . It works on the principle of Zener breakdown and is operated in reverse breakdown region. In reverse breakdown region high current flow through the diode leading to high power dissipation.
Now the question arises where this type of diodes are used.
The main application of this type of diodes are as voltage regulator.
Over voltage protector, as voltage reference.
We will discussed what is the application of zener diode as voltage . The nearest preferred value is 5. Where different levels of voltage are . Some of these are: voltage stabilizers or regulators (in shunt mode), surge suppressors for device protection, peak clippers, switching operations, reference elements and in meter protection applications. A zener diode is always operated in its reverse biased condition. A voltage regulator circuit can be designed using a .
