Answer 2

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........

Answer 3

A Zener diode is a type of diode that permits current to flow in the forward direction like a normal diode, but also in the reverse direction if the voltage is larger (not equal to, but larger) than the rated breakdown voltage known as "Zener knee voltage" or "Zener voltage". A tunnel diode or Esaki diode is a type of semiconductor diode which is capable of very fast operation, well into the microwave region GHz, by utilizing quantum mechanical effects. It was named after Leo Esaki, who in 1973 received the Nobel Prize in Physics for discovering the electron tunneling effect used in these diodes. These diodes have a heavily doped p-n junction only some 10 nm (100 Å) wide. The heavy doping results in a broken bandgap, where conduction band electron states on the n-side are more or less aligned with valence band hole states on the p-side.

Answer 4

The very basic difference among the two is there reverse breakdown voltage.

The zener diodes are more heavily doped then the PN diode and the usually their breakdown electric fields differs by 3 orders.

Answer 5

Schottky diode

is a special type of diode with low voltage. When current flows through the diode will be detained by the internal resistance, which causes a small voltage at the diode terminals. Normal diode between 0.7-1.7 volts, while the Schottky diode voltage approximately between 0.15-0.45 volts. Schottky diodes using metal-semiconductor junction as a Schottky barrier (of a semiconductor-semiconductor junction as in conventional diodes). Schottky barrier is produced by the contact time is very fast and low voltage. Differences pn and Schottky diodes are of the reverse recovery time, when switching from state to state does not conduct and conduct contrary. Where in the pn diode recovery time can be of the order through hundreds of nano-seconds and less than 100 nano-seconds for fast diode.

Answer 6

Zener diodes and regular diodes are different in a couple of ways. Zener diodes are made of silicon like a regular diode but the silicon is more doped in a Zener diode. Zener diodes also have a reverse-biased flow rather than the forward-biased flow of a regular diode.

Answer 7

A: No difference except that the reverse voltage breakdown of the pn junction cannot be predicted in value
