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.

How do you distinguish yield point and elastic limit?
On a stress strain curve the elastic limit is the point where the straight portion curve first starts to curve. When load is removed strain will return to zero. The yield point is a point on the curve just beyond the elastic limit. When load is removed strain will not return to zero. It will return approximately as a straight line parallel to the original, and have an offset strain value. The yield point offset is arbitrary but usually defined as 0.2% (.002 permanent strain) as most common strain devices can measure that amount.
Why a stress strain curve usually has two segments?

Why the dynamic resistance of a zener diode different from its static resistance?
The dynamic resistance of a diode, be it zener or otherwise, will be different from its static resistance because a diode is not a resistor, and resistance is not a function of current flow. It is a diode, and a diode has its own characteristic voltage to current curve, forward and, in the case of a zener, reverse.
What is LED characteristics curve?

What is the characteristic shape of logistic growth curve?
The classic "S" shaped curve that is characteristic of logistic growth.
Is it possible to check diode and zener diode in laboratory?
yes, of course it is. one way is using a curve tracer.
What is the main characteristic of a diode?
It conducts in only one direction.
Which diode used for signal amplification zener or schottky or tunnel or none?
The diode that has a negative resistance region in its voltage-current curve.
Is diode characteristic symmetrical?
Absolutely not. An ideal diode's characteristic would be perfect conduction in the forward direction and perfect insulation (no conduction) in the reverse direction. Silicon diodes come respectably close.
What is the incremental resistance obtained from the diode equation?
The incremental resistance of a diode is the inverse of the slope of the V-I curve at the operating point.
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
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.
What is the characteristics shape of a logistic growth curve?
