Which of the following statements is (are) true about reverse bias breakdown due to impact ionization and Zener tunneling?
Reverse bias breakdown due to impact ionization is when electrons are accelerated by the electric field to such high speeds that they knock other electrons out of the atoms they collide with. This process releases a large amount of energy, which can cause the breakdown of the material. Zener tunneling is when the electric field is strong enough to cause the electrons to tunnel through the potential barrier. This process can also cause the breakdown of the material.
Indium Phosphide diode Working?
It works on the principle of gunn effect. It has three valleys.....
How large do you think the needle is in the scanning tunneling mircoscope?
Needle in the scanning tunneling microscope is about 10 nanometers.
What does a scanning tunneling microscope allow scientists to see?
The scanning tunneling microscope scans samples using a very fine metallic tip.
You can see atoms using a scanning tunneling microscope?
The needle doesn't actually touch the atoms, but you can their outlines.
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 an ideal zener diode and practical zener diode?
Zener diode is heavily doped pn junction diode.
When a 6 V zener diode is series with a 12 V zener diode what is the effect?
If they are both connected in the correct direction, and they are both rated for close to the same power dissipation (approx the same physical size), then you have created an 18-V zener diode.
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
Does a zener diode acts as a switch?
A zener diode cannot be used as switch.
Who invented the zener diode?
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
When operating as a voltage regulator the breakdown in a Zener diode occurs due to which effect?
avalanche
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.
What is the difference between p n junction and zener 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.
When a 3.3 V zener diode is parallel with a 7 V zener diode what is the break down voltage?
Since they are in parallel, the 3.3V zener diode will "kick in" first when you reach 3.3V, and the circuit will pretty much act the same as if the 7V zener diode isn't there at all.
