Unless the LED is a dual color LED, its reverse characteristics are similar to an ordinary diode.
doping concentration,temperature are the major source of reverse current
A: That is no such a diode but if it exists it will have unlimited reverse voltage capability the forward voltage drop will be zero no matter of current flow and it will remain so regardless of temperature changes
What is the cause of reverse recovery time in a pn junction diode
negative tempareture It depends on the reverse voltage. Up to about 5.6 volts, the zener has a negative temperature coefficient. Beyond 5.6 volts it begins to show a positive temperature coefficient.
what is the difference between reverse characteristics of zener diode and a practical diode ?
Unless the LED is a dual color LED, its reverse characteristics are similar to an ordinary diode.
The VI characteristics of PN junction diode when used as a diode rectifier are reverse bias and rectification is shown by an asymmetrical current flow.
Reverse saturation current of germanium diodeThe current that exists under reverse bias conditions is called the reverse saturation current. Reverse saturation current of the germanium diode is typically 1 micro ampere or 10-6 a.At a fixed temperature, the reverse saturation current of a diode increases with increase in applied reverse bias. In reverse bias region the reverse saturation current also varies with the temperature.
doping concentration,temperature are the major source of reverse current
Most diode voltage stays negative and linear with temperature effects. To combat the temperature, current must remain steady within the diode, and it should not heat with that applied current.

1/T
No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.
A: heat And PIV(Peak Inverse Voltage) or so called Peak Reverse Voltage is limit the diode characteristics.
