Zener Diode Breakdown Voltage. The point at which the zener voltage triggers the current to flow through the diode can be very accurately controlled (to less than 1% tolerance) in the doping stage of the diodes semiconductor construction giving the diode a specific zener breakdown voltage, ( vz ) for example, 4.3v or 7.5v. Zener diode is a special kind of diode that allows current to flow in the forward direction in the same manner as an ideal diode, but also permit it to flow in the reverse direction when the voltage is above a certain value known as the breakdown voltage of zener diode, zener knee voltage or zener voltage.

The zener diode is rated for 5.1v, well below the 9 volts supplied. Zener voltage refers is the reverse breakdown voltage, which ranges from 2.4 v to 200 v; On the one hand, the zener breakdown voltage zk v of a junction diode:
This Is An Important Feature Of The Zener Diode, Which Can Be Used In Voltage Regulator Applications.
In breakdown the voltage across the zener diode is close to constant over a wide range of currents thus making it useful as a shunt voltage regulator. The voltage must be higher than the rated zener voltage of the zener diode. * is typically large (e.g., 50 v or greater).
A Zener Diode Is A Normal Diode Designed With A Specific Breakdown Voltage.
Zener diode is a special kind of diode that allows current to flow in the forward direction in the same manner as an ideal diode, but also permit it to flow in the reverse direction when the voltage is above a certain value known as the breakdown voltage of zener diode, zener knee voltage or zener voltage. V = v z + i. What this means is that when their reverse breakdown voltage is exceeded, they will start to conduct current.
The Zener Voltage Refers Is The Reverse Breakdown Voltage, Which Ranges From 2.4 V To 200 V;
Just as importantly, zener diodes with hundreds of values of v z are commonly available, making them easy to design a circuit with. Zener diode as a voltage regulator. Some commonly used specifications for zener diodes are as follows:
The Voltage Across The Zener Diode In Breakdown Region Becomes Almost Independent Of The Current Through It.
Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. The symbol of zener diode is shown in below figure. The zener diode is rated for 5.1v, well below the 9 volts supplied.
From The Discussion Of The Diode Characteristic Curve In Previous Article, That When A Diode Reaches Reverse Breakdown, Its Voltage Remains Almost Constant Even Though The Current Changes Drastically, And This Is The Key To Zener Diode.
At zener breakdown voltage the current starts flowing in the reverse direction. The graph of the zener breakdown is not exactly vertical shown above which shows that the zener diode has resistance. The point at which the zener voltage triggers the current to flow through the diode can be very accurately controlled (to less than 1% tolerance) in the doping stage of the diodes semiconductor construction giving the diode a specific zener breakdown voltage, ( vz ) for example, 4.3v or 7.5v.
