whether we know that p-n diode is real diode. But still in case of semeconductor we see then silics is real diode.

Why you use real diode instead ideal diode?

Ideal components do not exist in the real world. They are only simplified descriptions of components used to create models to help understand the behaviour of components in circuitry. Its not possible to use something that doesn't exist.


How real diode is different from ideal diode?

It depends how "ideal" your ideal diode is. The first approximation of an ideal diode is that it's a device that allows current to flow one way, and not the other way, while doing this with no losses. The second approximation of a diode implies the inherent 0.7V drop across the device, as well as one way current flow, but with no loss resistance. The third approximation of an ideal diode is a device which allows current to only flow one way through it, with a 0.7V loss across is, as well as a small internal resistance of a few ohms. These all vary from a real diode because these are all linear, in every sense. You can neither calculate the voltage nor the current across/through a diode. Instead, you must use the diode's characteristic curve (given on datasheet), and linearize it. You can get any amount of current to flow through the diode the CORRECT direction, by changing the voltage used. A number of microamps will take perhaps, a third of a Volt.

What is the output of a diode can be?

A diode itself has no input or output.The circuit containing the diode usually has an input and an output, maybe even more than one of each. The output of this circuit will depend on far more than the diode as well as depending on the type of diode used.Theoretically: if a diode is connected across the secondary output of a stimulated transformer, you would read a half wave at the frequency of the source across diode.Such a circuit would cause any real diode to explode due to lack of any current limiting and the resulting high power dissipation in the diode.Hence "Theoretical". That's kind of what "Theoretical" means.
