Zener Breakdown and Zener Characteristic

The width of the depletion region is quite narrow in heavily doped semiconductor diode. Let us consider a heavily doped semiconductor diode in reverse bias condition. Here the width of the narrow depletion region (due to high doping) leads to a high electric field developed across the junction since the electric field equals to the … Read more

What is Avalanche Breakdown?

A p-type semiconductor material in contact with an n-type semiconductor material forms a p-n junction in which a depletion region occurs around the plane of contact. The width of this depletion region is seen to vary depending on the bias applied at the terminals of the p-n junction i.e. an increase in the applied voltage … Read more
