A zener diode has a contact potential of 1 V in the absence of biasing. It undergoes Zener breakdown for an electric field of 10^(6) V/m at the depletion region of p-n junction. If the width of the depletion region is 2.5 mu m, what should be the reverse biased potential for the Zener breakdown to occur ?

A certain p-n junction, having a depletion region of width 20 mum , was found to have a breakdown voltage of 100 V. If the width of the depletion region is reduced to 1 mu m during its production, then it can be used as a Zener diode for voltage regulation of

A zener diode has a contract potential of 0.8 V in the absence of biasing. It undergoes zener breakdown for an electric field of 10^(6) Vm^(-1) at the depletion region of p-n junction. If the width of the depletion region is 2-4mu m, what should be the reverse biased potential for the zener breakdown to occur?
