Backward diode
A: A zener is a diode that when connected in the reverse mode current direction it will breakdown to a predetermined voltage any further increasing voltage the breakdown will remain practically the same.
efreqw
The capacitance of a varicap diode varies as the reverse voltage to the diode changes. As you increase the reverse voltage, the capacitance decreases. And vice versa.
Reverse-biased ---from the book of Malvino
wat's d application of trappat diode
Advantages of Trapatt:• higher efficiency than impatt• very low power dissipationAdvantages of Impatt:• This microwave diode has high power capability compare to other diodes.• Output is reliable compare to other diodes.
Backward diode
switch is similar to diode action
what is the basic operation of LED
A Tunneldiode, usually made of GaAS. In a part of its curve it has a negative resistance. This means that when you increase the voltage in that region, the current will drop.

by using a suitable diagram, explain the one of the operation in microwave energy sources except Guinn Diode.
Reverse-biased ---from the book of Malvino
A: The principle is that is a semiconductor meaning will conduct one way only. A switching diode however will have the least of capacitance across its junction so when it disconnect is faster
