Zener breakdown will occur if : |
Impurity level is low Impurity level is high Impurity is less in n-side Impurity is less in p-side |
Impurity is less in p-side |
Zener breakdown occurs when we apply reverse bias to a heavily doped diode. In a reverse bias situation, ideally no current flows for a p-n junction diode, the diode acts as an open switch. |
