☑ Forward Bias Characteristics Of Zener Diode

But due to higher doping concentration higher current flows through the zener diode. In the third quadrant the magic happens.

2 4 the reverse current is typically less than 110000 of the lowest normal forward current level.

Forward bias characteristics of zener diode. When a forward voltage is applied current flows through it. When the diode is connected in forward bias diode acts as a normal diode. For a diode with the characteristics in fig.

When forward biased voltage is applied to the zener diode it works like a normal diode. A graph of current through vs the voltage across the device is called the characteristic of zener diode. Here the zener diode acts like an ordinary diode.

It means that the anode must be connected to the negative side of the voltage source and the cathode must be connected to the positive side. However when reverse biased voltage is applied to the zener diode it works in different manner. Vi characteristics of zener diode.

The first quadrant is the forward biased region. Therefore i r is quite negligible when compared to i f and a reverse biased diode may be treated almost as an open switch. When the reverse bias voltage is greater than a predetermined voltage then the zener breakdown voltage occurs.

Zener diodes are normally used only in the reverse bias direction. A main difference between zener diodes and regular silicon diodes is the way they are used in the circuits. A zener diode is a silicon semiconductor device that permits current to flow in either a forward or reverse direction.

The diode consists of a special heavily doped p n junction designed to conduct in the reverse direction when a certain specified voltage is reached. Characteristics of a zener diode the above diagram shows the v i characteristics of the zener diode behavior. The vi characteristics of a zener diode is shown in the below figure.

In forward bias operation the diode act like a closed switch. In this article we learn about pn junction diode characteristics in detail like how to bias a pn junction forward reverse bias methods behavior of pn junction during forward reverse bias setups how to plot the vi characteristics what is reverse breakdown and many other essential concepts regarding a pn junction diode. A diode is forward biased if the p type pin is connected with the anode of a voltage source and n type of the diode is connected with the cathode of the source.
