The reverse characteristics of a diode are significantly influenced by temperature. As temperature increases, the reverse saturation current also increases due to the enhanced thermal generation of charge carriers, leading to a higher leakage current. This can result in a lower breakdown voltage and a shift in the reverse voltage characteristics. Additionally, the temperature dependency can affect the diode's overall reliability and performance in circuit applications.

What are the reverse characteristics of an led?
Unless the LED is a dual color LED, its reverse characteristics are similar to an ordinary diode.
What are the sources of reverse current in a diode?
doping concentration,temperature are the major source of reverse current
What is an ideal diode?
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 type tempcoefficient does the zener diode have?
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.

Reverse saturation current of Ge diode?
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.

Effect of temperature on diode?
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.
How does the reverse saturation current of P-N diode varies with temperature?

Will a zener diode work the same as a germanium diode?
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.
What are the limiting values of a PN junction Diode?
A: heat And PIV(Peak Inverse Voltage) or so called Peak Reverse Voltage is limit the diode characteristics.

ginago
What is V-I characteristics of zener diode?
Work in reverse bias.(breakdown at a particular voltage to keep the volt. constant so used as voltage regulator) same as diode when forward biased.
