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.
When a diode is connected in a Reverse Bias condition, a positive voltage is applied to the N-type material and a negative voltage is applied to the P-type material.
A zener diode is also a type of diode that allows reverse current to flow through it, if the voltage exceeds the breakdown voltage known as 'Zener Voltage.
Diode is a pn junction device which conducts (current flow)in forward direction.
Zener diode is a device in which current flows in forward direction as well as in reverse direction.For a Zener diode,current flows in reverse direction if the voltage is larger than the breakdown voltage,where the breakdown voltage is the minimum reverse voltage to make the diode conduct in reverse.
a rectifier conducts in the forward direction.
a zener conducts in the reverse direction in zener breakdown mode.
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.
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
ZENER DIODE IS MADE TO REVERSE BREAK OVER AT A CERTAIN VOLTAGE the break over knee is not exactly sharp especially in low voltage zeners. and p-n means positive and negative junction
A zener diode cannot be used as switch.
Zener diode is heavily doped pn junction diode.
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.
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.
The difference is , the break down in a zener is desirable, well designed, expected, healthy and designed for a particular value. After breakdown, it can and is expected to maintain that condition for a long time. zener is optimized to work in this region.They are designed to have very low breakdown voltages. In contrast, the break down in a rectifier diode is undesirable, not well designed, not respected. This diode is optimized to work in the rectifier region and optimized for that. Breakdown region is avoided in normal operation. The breakdown voltage is normally very high, above 100 volts.
what is the difference between reverse characteristics of zener diode and a practical diode ?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
you basically use rectifiers..like zener diode rectifier and full bridge rectifier..
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.

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.
