Which diode have characteristics very close to that of an ideal voltage source?
zener diode
How much current draw zener diode?
It depends on the particular zener diode. Typically, they will pull 75 ma of current.
What type of diode maintains constant current?

What is the expression for calculating maximum current through the zener diode?
the expression for calculating maximum current through the zener diode is : Izmax=Pzmax / Vz
Does zener diode utilize a larger current?
A zener diode, in the reverse bias condition, presents a higher voltage. The current, however, is a function of the supplying circuit.

The Zener diode has the characteristics of a constant voltage source.
How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
What is the difference between an ideal zener diode and practical zener diode?
Zener diode is heavily doped pn junction diode.
What is the leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
What is leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
When current through a zener diode increases by a factor of 2 by what factor does the voltage across the zener diode increase?
If the zener diode is in zener breakdown the voltage across the zener diode remains constant regardless of current (for the ideal zener diode). Real zener diodes have parasitic resistance that causes the voltage across the zener diode to increase slightly with increased current, but due to temperature dependant variations in this parasitic resistance as well as temperature dependant variations in the zener breakdown voltage, this change in voltage in real zener diodes cannot be described by a simple linear factor.
How much current draw zener diode?
It depends on the particular zener diode. Typically, they will pull 75 ma of current.
What is zener dioide?
Zener diode can be defined as diode which allows current to flow in the forward direction in the same method as an ideal diode, but will also allow it to flow in reverse direction when the voltage is above definite value known as the breakdown voltage
What type of diode maintains constant current?
zener diode
What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
What is the difference between rectifier diode and zener diode?
A: They are both diodes. The difference lies in the application. A rectifier is used to rectify AC current into pulsating current. The zener diode is used to regulate a voltage source to the zener voltage when connected in the reverse direction. ************************************************************** If you look at the characteristic curves of a rectifier diode and a zener diode, you will see that they are similar, but the reverse curve of the zener has a much sharper bend at what is called the "knee". It is at this point on the zener's curve at which it operates.
