What is the breakdown voltage of 1N4007 diode?
The reverse breakdown voltage of the 1N4007 diode is 1000 volts.
Define rms reverse voltage of a diode?
A DIODE will breakdown at a certain reverse voltage if RMS VOLTAGE IS SPECIFIED THEN the actual voltage will be RMS volts times 1.41
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.
At what value reverse breakdown voltage should ouccer of normal diode?
its about 1000 v
What are specifications of pn junction diode?
This can vary significantly from diode to diode (especially the reverse recovery time and peak reverse breakdown voltage), so always consult the datasheet.

Why does voltage remain constant in the reverse breakdown region in a zener diode?
This space is for answering "http://wiki.answers.com/Q/Why_does_voltage_remain_constant_in_the_reverse_breakdown_region_in_a_zener_diode" Why does voltage remain constant in the reverse breakdown region in a zener diode?
Difference between diode and zener diode?
All diodes have a tiny voltage when current flows in a 'forward' direction. And a Reverse Breakdown voltage when current tries to flow in a reverse direction resulting in a high voltage. That current does not flow until voltage exceeds its breakdown number. Regular diodes have a reverse breakdown voltage that is somewhere above a number, For example a 1N4002 has a Reverse Breakdown Voltage somewhere above 100 volts. A Zener diode is constructed so that its Reverse Breakdown voltage is clearly defined and accurate. For example Reverse Breakdown voltage for a 1N4733 is 5.1 volts. A !N4734 is 5.6 volts.
What is Meaning of diode rating?
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
What resistance does a practical diode offer under reverse-biased conditions if the applied reverse voltage is greater than the breakdown voltage?
A normal diode with reverse voltage in excess of its rated breakdown voltage could fail. Resistance could be high (blown open) or low (shorted).
What resistance does a practical diode offer under reverse-biased conditions if the applied reverse voltage is less than the breakdown voltage?
A practical diode under reverse-biased conditions, if the applied reverse voltage is less than the breakdown voltage, will offer a high resistance, usually in excess of 10 megohms. In a practical circuit, the diode would appear to be open.
What is zener break down voltage?
The point in the forward operating region of the characteristic curve where conduction starts to increase rapidly is called Knee voltage of a PN Junction Diode.The breakdown voltage of a diode is the minimum reverse voltage to make the diode conduct in reverse.(or) Breakdown voltage is a parameter of a diode that defines the largest reverse voltage that can be applied without causing an exponential increase in the current in the diode.-- Dinakar
How are power diode classified?
by reverse breakdown voltage & forward current capacity
Break down voltage?
The breakdown voltage of an insulator is the minimum voltage that makes it partially conductive electrically. On the other hand, the breakdown voltage in a diode refers to the minimum reverse voltage to cause it to conduct in reverse.
What is the difference between rectifier diode and zener diode?

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".

What does it means when we say-diode is specially designed to operate under reverse bias in breakdown region?
You are talking about a special type of diode called a zener diode which is designed, using special junction doping, to allow controllable reverse bias operation at a reduced breakdown voltage with a much sharper knee point curve than its normal forward breakdown curve. This allows the diode to be used as a voltage regulator. Normally, a diode's reverse breakdown curve is such that, at reverse breakdown, it avalanches and, without current limits in place, will self destruct. The zener diode, on the other hand, will operate in reverse much the same as it does in forward, just at a different voltage, and with a much sharper current to voltage curve, making it highly suitable as a voltage regulator.
