It's a rectifier diode made simply by combining P type and N type silicon. Where the two are joined, forms a junction that allows conduction in one direction only.

A pn junction diode is a diode obtained by by dopping a silicon crystal through the process of covalent bond.

When p-type and n-type semiconductor is connected to each other and difusion takes place there then this arrangement is called p-n junction diode.

Why use the PN junction diode in rectifier?

We use pn junction diode in rfctification as a rectifier becase it allows current to flow in one direction only, i.e. in forward biase only , and stop current to flow in reverse baised. thats why we use pn junction diode in rectification.

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.


Why tunnel diode are used in negative resistance region?

because that the tunnel diode is a standard pn junction diode in many respect except its highly doped pn junction so it has some characteristics in the negative resistance region another that its a standard diode
