What are examples of diodes?
There are so many different types of diodes. Some of the common examples include light emitting diodes, silicon diodes, zener diodes and so many more.
Why current flow from cathode to anode in zener diode?
First off, I don't know if by current flow you mean conventional current flow or electron current flow. You realize they are in opposite directions and most electronics engineers use conventional current flow in circuit analysis.Ignoring this, I will assume your real question is "Why does current flow backwards in zener diodes compared to ordinary diodes?" The answer is that zener diodes are not operated in the forward biased range as are ordinary diodes, instead they are operated in the reverse biased range. When reverse biased enough any diode reaches breakdown voltage and suddenly conducts. Most ordinary diodes can be destroyed by breakdown, but zener diodes are designed to tolerate it. In zener diodes, this breakdown is referred to as "zener breakdown" and the voltage it happens at the "zener voltage".Low voltage zener diodes can still be used in the forward biased mode, like ordinary diodes. However most high voltage zener diodes have a "blocking diode" that is not documented on the data sheet to block forward biased operation. "Blocking diodes" are simply ordinary diodes wired in series with the zener; when the zener would be forward biased they are reverse biased (and thus blocking current), when the zener would be reverse biased they are forward biased.
Is superposition theorem applicable for diodes?
No, diodes are not linear elements like resistors are. Current can only flow in one direction in diodes.
Why diodes does not work properly in high frequency?
Diodes have capacitance, placing a limit on their switching rate.
What happens if one of the four diodes in s bridge rectifier is reverse?
four diodes
What is the difference between placing a reverse protection diode in series or in parallel to the supply?
A: big difference diodes are semiconductor with the right polarity it can be a short to the power supply reversing will cause no problem and probably eliminate some spikes
What purpose does an Alternator Diode serve on a 96 Jeep Cherokee 4.0?
DIODES ONLY SERVE ONE PURPOSE , THEY LET THE ELECTRIC FLOW IN ONE DIRECTION ONLY..........SO IT IS PROBABLY THERE TO KEEP THE ALTERNATOR FROM REVERSING POLARITY.
What are the major classification of diodes?
1. general purpose diodes 2. fast recovery diodes 3. schottky diodes
What are examples of diodes?
There are so many different types of diodes. Some of the common examples include light emitting diodes, silicon diodes, zener diodes and so many more.
Are diodes rectifiers?
No. Diodes are diodes. One diode can be USED as a half-wave rectifier. Four diodes can be used to build a bridge rectifier.
When was The Diodes created?
The Diodes was created in 1977.
When did The Diodes end?
The Diodes ended in 1982.

What are the classifications of diodes?
a diode is a device that alows current to flow in one direction you have power diodes which are used in rectification processes and high current operations but the two main families of diodes are solid state diodes or valve operated diodes.
When was Diodes Incorporated created?
Diodes Incorporated was created in 1959.
What is Diodes Incorporated's population?
Diodes Incorporated's population is 3,900.
What is the population of Diodes Incorporated?
The population of Diodes Incorporated is 2,010.
