It's a diode that is used to limit a voltage to some desired value. Importantly, it's used to limit a transient voltage or an alternative voltage.
The simplest example is that diode placed across a relay's inductive coil.
As current is cut off through the coil, a large induced voltage appears that can cause damage to the circuit.
A diode can be placed in circuit to catch/damp the induced voltage.

Why an op-amp diode rectifier called as a precision rectifier?
In a rectifier made of just diodes, the diodes have a voltage drop, resulting in a lower DC output voltage. By introducing an Op-amp, this voltage drop can be overcome. Since there is no voltage drop caused by the diodes, the rectified signal is not changed by the rectifier, so it is called a precision rectifier.
What is the difference between series and parallel diodes?
Connecting diodes in series:Connecting diodes in series will increase the forward voltage of the resultant diode.Connecting diodes in series will cause an open circuit until peak inverse voltage (smallest diode) is applied on total resultant.Connecting diodes in parallel:Connecting diodes in parallel will increase the current carrying capacity of the diode.Connecting diodes in parallel will not get you a resultant diode conduction in both sides.
Why not gate is not possible using diodes?
Diodes cannot invert, a required part of the not operation.
What are the applicaton of diodes?
Diodes can be used in the following domains:In rectifier circuitsin display circuitsas switches
How many type of diode?
There are many types of diodes that are used for different functions in electronics. The most common types include the laser diodes and the light emitting diodes (LED).
What are light detectors called?
Photo-diodes.
When is the Catching Fire coming out?
September 2009, tentatively. It will be called Catching Fire.
What are zenna diodes?
They are actually called zener and I think they limit the voltage of a circuit.
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 is the tool called used to tap the tree for water in Catching Fire?
The tool used to tap the tree for water in Catching Fire is called a spile.
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.
