there are many uses.
one major use i remember is in rectification i.e convert ac to dc
For switch operation
The use of the pn diode is for rectification. It can also be used as a switch.
PN junction dodies are used in rectifiers,electronic circuits
because that the tunnel diode is a standard pn junction diode in many respect except its highly doped pn junction so it has some characteristics in the negative resistance region another that its a standard diode
It means that the semi conductor have only one pn junction
No. You cannot create a transistor by connecting two diodes together. There is an interaction between the junctions of a transistor, said interaction being not possible when two diodes are connected together.
pn junction diode conducts current in one directions where as the zener diode conducts in both the directions. large current flow damage the PN junction diode but zener diode conducts eventhough there is a large current........
Diode is a two terminal semicon. Diode is a Switching device
The use of the pn diode is for rectification. It can also be used as a switch.
We use pn junction diode in rfctification as a rectifier becase it allows current to flow in one direction only, i.e. in forward biase only , and stop current to flow in reverse baised. thats why we use pn junction diode in rectification.
diode is unipolar
another name for diode is "pn" junction.
zener diode
Never. It is impossible to use diodes for amplification.
no....is n't
Zener diode is heavily doped pn junction diode.
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
what is the difference between reverse characteristics of zener diode and a practical diode ?
because that the tunnel diode is a standard pn junction diode in many respect except its highly doped pn junction so it has some characteristics in the negative resistance region another that its a standard diode
semiconductor diode with out a pn junction.
