No, we don not consider the barrier voltage of a diode to be able to act as a voltage source. The barrier voltage arises during construction of the p-n junction, and it results from charge separation. Separating charges results in voltage, but this difference of potential cannot be tapped as a voltage source because it cannot supply current the way we understand conventional voltage sources are able do.

∙ 11y agoNo,
As far as i know there are no Diode in the market which can be used like Voltage source--
But for your curiosity i am going to explain something which is relevant.
1> Mostly all Diodes consist a P-N junction(formed a diode).
2> A P-N junction which generates the voltage is Known as SOLAR CELL
although it has different fabrication process from conventional diodes.
3>so we can say that solar cell is a diode which works as voltage Source.

How much voltage appears across a zener diode when it is forward-biased?
That depends on the zener voltage rating:"low voltage" zeners are just a simple single diode, the zener diode"high voltage" zeners contain 2 back to back diodes in one package, the zener diode and an ordinary diode that is reverse biased when the zener diode is forward biased to block forward conduction of the zener and protect it from overcurrent damage if installed backwards by mistakeThus in "low voltage" zeners when forward biased they will have a normal diode drop (e.g. 0.7V), but "high voltage" zeners when "forward biased" they will act open due to the reverse biased blocking/protection diode in series with the zener.
What is Zener diode function?
Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, aZener diode conducts when the voltage reaches the diode's reverse breakdown voltage.
Why diode act as an insulator?
Diode is a semiconductor material. so it act as insulator also.
Why diode is active device when all other active devices require external power supply?
A Device is said to be active if... (i) It is a source of Power in the circuit... (ii) It amplifies any voltage or current in a circuit... (iii) It acts as a switch ie., has modes equivalent to ON and OFF... e.g., transistor amplifies and can also act as a switch...
What is a diode and how does it work?
When varactor diode is reverse biased then the neutral region between P and N layer increases. When reverse biasing decreases then the neutral region also decreases.
Can a diode act as a source of emf?
NO
How do you xxplain the zener shunt regulator?
zener diode is a special type of pn junction diode that work in breakdown region . There are two types of brekdowns in zener i.e avlanche breakdown and zener breakdown depending on the doping concentration. A zener diode in an on state can be considered as a voltage source ,equal to its zener voltage n hence act as an voltage regulator
What is unilateral element?
When an element polarity of voltage or current source changes, the magnitude of the corresponding current or voltage changes is called unilateral element. Eg: Diode Even Diode connected back to back in parallel act as a Bilateral.
What is the function of zener dioed?
The function of a zener diode is for it to act as a voltage regulator in the breakdown region.

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.
Why diode act as an insulator?
Diode is a semiconductor material. so it act as insulator also.
Why the n-jfet is operated with the negative voltage not the positive voltage?
In a JFET the only insulation between the gate and the channel is a reverse biased diode junction, if this junction becomes forward biased then the gate and channel are effectively shorted and the device no longer acts as a transistor (it will act as a forward biased diode instead). In the n-channel JFET, the gate is the P-side of this diode and the channel is the N-side of this diode. To keep this diode reverse biased (and the device operating as a transistor) therefor the gate MUST always be maintained at a voltage more negative than the most negative section of the channel.
What is the disadvantage and advantage of photo diode and transistor?
photo diode donot work for long distance photo diode act as a receiver
