The zener diode is optimized for reverse breakdown voltage accuracy and stability. This value and its tolerance is specified in more detail than a normal diode.

What is the difference between a diode and a Zener diode?

Normal Diode works in Forward Bias and Zener Diode works in reverse bias region.


What is the difference between an ideal zener diode and practical zener diode?

Zener diode is heavily doped pn junction diode.


What is the difference between p n junction and zener diode?

The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.


Can zener diode be used as rectifiers?

Yes **************************************** Yes they can but there are pitfalls. A normal diode will have a high reverse breakdown voltage. A zener has a relatively low breakdown voltage (its "zener"voltage). If a zener diode is used as a rectifier it must have a zener voltage at least twice the peak of the applied a.c.


What is Zener resistance of the Zener diode?

zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode


How we can make zener diode from pn junction diode?

A zener diode is made by using unusually high doping levels in both the p & n sides of the junction. As doping profiles cannot be changed after manufacture, it is not possible to convert a normal junction diode into a zener diode.


Should a zener diode be connected in the reverse bias direction?

Yes, a zener diode is normally operated in the reverse bias direction, cathode more positive than anode.If you forward bias a zener diode, it acts like a normal diode, with a junction voltage between 0.6V and 0.7V, which is not what you want.


What is a zener diode for?

zener diode is for regulator purpose. it will maintain the constant voltage so we are using as regulator. we have to connect reverse bias then only it will act like zener diode if we are connecting forword bias it will act like normal diode.............. H.L.Kiran


What is the forward voltage of a silicon based zener diode?

It would be 0.7V, the same as any other silicon diode; except for one thing, most zener diodes are manufactured with a reversed diode in series with them. When the zener is operated in its normal zener breakdown mode this reversed diode conducts, letting the zener operate. When the zener is operated in its forward biased mode this reversed diode prevents conduction. Thus most zeners have no forward voltage.


Zener diode with its forward biase?

acts like a normal diode in forward biased condition


Where are zener diode used?

zener iode is a special type of junction diode with different level of doping as compared to normal pn junction diode .... zener diode are used in reguled power supply to provide constant output voltage irrespective of change of input supply or load variations


What is the difference between p-n junction and zener diode?

pn junction diode conducts current in one directions where as the zener diode conducts in both the directions. large current flow damage the PN junction diode but zener diode conducts eventhough there is a large current........


What is the difference between rectifier diode and zener diode?

A: They are both diodes. The difference lies in the application. A rectifier is used to rectify AC current into pulsating current. The zener diode is used to regulate a voltage source to the zener voltage when connected in the reverse direction. ************************************************************** If you look at the characteristic curves of a rectifier diode and a zener diode, you will see that they are similar, but the reverse curve of the zener has a much sharper bend at what is called the "knee". It is at this point on the zener's curve at which it operates.


How much voltage appears across a zener diode when it is forward-biased?

That depends on the zener voltage rating:"low voltage" zeners are just a simple single diode, the zener diode"high voltage" zeners contain 2 back to back diodes in one package, the zener diode and an ordinary diode that is reverse biased when the zener diode is forward biased to block forward conduction of the zener and protect it from overcurrent damage if installed backwards by mistakeThus in "low voltage" zeners when forward biased they will have a normal diode drop (e.g. 0.7V), but "high voltage" zeners when "forward biased" they will act open due to the reverse biased blocking/protection diode in series with the zener.


How does a zener diode work in forward bias?

Like a normal diode............. unless it includes a "back biased" diode to prevent conduction in this mode as is common in zener diodes rated at about 10 volts or more, then it acts as an open circuit.


What is the function of zener diode?

zener diode is a revers bias diode which used for voltage regulation.


Why the zener diode is used as a semiconductor device in voltage regulator?

A zener diode is a special kind of diode, which permits current to flow in the forward direction as normal, but it will also allow current to flow in the reverse direction when the voltage is above a certain value. This break over vlotage is the zener voltage which the diode is named after. See Related Links below.


How zener diode differ from normal p-n junction diode?

Zener diodes differ from normal p-n junction diodes in that they have a reduced reverse breakdown voltage and, in fact, we normally operate zener diodes in reverse bias to take advantage of the relatively stable voltage regulation it provides.


Use of zener diode?

The zener diode is used for rectification and stabilisation.


What will happens if zener diode and resistance are connected in parallel?

When a zener diode is connected in series with a resistor, the voltage across the resistor will be stabilized by the zener diode.


What is the difference between zener diode and p-n junction diode?

zener diodes r power diode..........................they generally used in reverse bias . mainly they hav application in regulators..............


When current through a zener diode increases by a factor of 2 by what factor does the voltage across the zener diode increase?

If the zener diode is in zener breakdown the voltage across the zener diode remains constant regardless of current (for the ideal zener diode). Real zener diodes have parasitic resistance that causes the voltage across the zener diode to increase slightly with increased current, but due to temperature dependant variations in this parasitic resistance as well as temperature dependant variations in the zener breakdown voltage, this change in voltage in real zener diodes cannot be described by a simple linear factor.
