4 Questions
What happens when a small reverse biased voltage is applied to a heavily doped p-n junction diode?
Strong electric field is produced in a small width of depletion region
What causes the zener breakdown in a p-n junction diode?
Covalent bonds in the depletion region are directly broken up by a strong electric field
What is the result of a large force exerted on covalent bonds in a heavily doped p-n junction diode?
Covalent bonds are broken up and large electron hole pairs become free
What is the reverse bias voltage at which zener breakdown takes place called?
Zener breakdown voltage Vz
