A reverse-biased diode is typically operated in the reverse breakdown region of its current-voltage characteristic curve. In this region, the diode allows a small reverse current to flow, which is generally negligible until a certain breakdown voltage is reached. Beyond this breakdown voltage, the diode can conduct significant current, but in normal applications, it operates below this threshold to prevent damage. Thus, the diode primarily remains in the reverse bias region with minimal current flow.
What else can I help you with?
Why there is no current in reverse bias condition?
Current flows in a reverse biased diode because diodes are not ideal. They do have leakage current and a breakdown voltage in reverse, just as they have a breakdown current in forward and a non-linear and non-parallel forward voltage to current curve. It is also possible that you are looking at a zener diode. A zener diode is specifically design to conduct at a certain voltage in reverse.
Discussion of zener diode a voltage regulation?
A zener diode has a relatively flat voltage to current curve when reverse biased. Within limits, you can consider that the voltage across the zener diode is constant. You can use the zener as the primary regulator, so long as you consider the power requirements and dissipation of both the zener and the load, and you do not overload the zener. More often, the zener is used as a voltage reference in a larger power supply that uses other components, linear or switched, to supply the load.

Draw and explain the v-i characteristics of a p-n junction?
As you can't draw here, see link.In the forward bias voltage direction (right side) current slowly rises until the knee is at 0.7V in silicon diodes (0.2V in germanium diodes), then current rapidly rises. The forward biased V:I curve closely approximates an exponential function.In the reverse bias voltage direction (left side) current stays constant at near zero, until the breakdown voltage is reached then jumps to a high value.
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
In what region of their characteristic curve are zener diodes operated?
Zener diodes are normally operated in their reverse breakdown voltage curve.

The characteristic curve of a diode?
A diode characteristic curve is a curve that describes the characteristic of diode and it is normally based on experiment data. The curve itself has two distinctly separate parts.One part lies in the first quadrant and it stands for the forward-biased situtation.It reflets the barrier voltage(meaning the smallest amount of voltage that can turn on the diode).For Germannium diode,the barrier voltage is 0.3V while silicon diode is 0.7V,but the real value differs according to the temperature and current flows through the diode.The other part lies in the third quadrant which indicates the reverse-biased situation,from which you can find out the leakage current(the current flow through before Breakdown Point). Typcially, a diode characteristic curve varies from diode to diode.But theoretically speaking,we regard them as the same.
Does zener diode works after breakdown voltage?
Yes. The intended use of a zener diode is to be reverse biased at the breakdown voltage. In this mode, the zener has high slope in the current to voltage curve, making it a good choice for voltage regulation.
What does the base curve in eyeglasses mean?
Base Curve normally refers to the front curve of the lens. they can range from 1 Diopter of curve to 10 Diopters of curve (normally used for really wrapped Sunglasses like Ray-Ban, Oakley)
Does a cube have a curve surface?
Not normally
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.
How much is a blackberry curve on contract?
It depends which one you want...The BB curve 8250 is normally around £15 per monthThe BB curve 9300 is normally around £20- £30I dont know about the older ones like The BB curve 8900 and that.
Which diodes has a characteristic curve with both a forward and a reverse breakover?

Normally just 1 circular curve
Why is the ordinary demand curve flatter than a compensated demand curve if the good is a normal good but the reverse is the case if the good is inferior?
because the ordinary demand curve ignores the income effect of price changes.also since the compensated demand curve is less inelastic than an ordinary demand curve.
Why zener diode used as voltage regulator?
It has a very sharp reverse breakdown voltage curve and is not damaged by the reverse current, as some normal diodes might be.
