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

Anonymous

∙ 14y ago

Updated: 11/19/2022

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.

How do you xxplain the zener shunt regulator?

zener diode is a special type of pn junction diode that work in breakdown region . There are two types of brekdowns in zener i.e avlanche breakdown and zener breakdown depending on the doping concentration. A zener diode in an on state can be considered as a voltage source ,equal to its zener voltage n hence act as an voltage regulator

What is zener diode and for what it is used?

Zener Diode is nothing but a Crystal P-n junction diode in which the P type and n-type layers are heavily doped.Zener diode is mainly used as voltage regulator its forward charaqcteristic is same as normal p-n junsction diode but its reverse Characteristic is different that when the reverse region reaches knee region in spite of changes in current the voltage remains the same

How is zener diode different from p-n junction diode?

A p-n junction diode is made of a crystal of semiconductor. Impurities are added to it to create a region on one side that contains negative charge carriers (electrons), called n-type semiconductor, and a region on the other side that contains positive charge carriers (holes), called p-type semiconductor. A Zener diode contains a heavily doped pn junction allowing electrons to tunnel from the valence band of the p-type material to the conduction band of the n-type material. A reverse biased Zener diode will exhibit a controlled breakdown and let the current flow to keep the voltage across the Zener diode at the Zener voltage.

What is the function of zener?

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

Can a transister base-emitter junction be used as a zener diode?

No, the doping profile is entirely wrong. Also some transistors have very low reverse breakdown voltage on the BE junction and will burn out!

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.

Difference between zener diode and junction diode?

Zener diodes and ordinary junction diodes are similar, except that zener diodes have additional doping to bring their reverse breakdown voltage into a more usable value, and to allow them to not destructively avalanche when they do conduct in the reverse direction.

What is the primary difference between a zener diode and PN-junction Diode?

Can zener diode used as rectifier?

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.
