What indicate 1 in 1N4007 diode?
general purpose diode with 1000V reverse breakdown.
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?
How are power diode classified?
by reverse breakdown voltage & forward current capacity
What happens in the circuit when a1N4001 diode experiences its breakdown voltage of 50V?
If a diode breaks down in the reverse direction then, providing there is current-limiting resistance, nothing will happen to the diode. If there is no such current-limiting resistance the diode will be destroyed. Heat is the only enemy of a semiconductor of this type.
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.

A typical value of reverse breakdown voltage in a diode is?
50V or larger
What is breakdown condition?
all most 50Volts when diode is in reverse bias.
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.

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.
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
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.
