  • A zener diode has a contact potential of in the absence of biasing. It undergoes Zener brea

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

Option: 1

\mathrm{3.5\ V}


Option: 2

\mathrm{2.5\ V}


Option: 3

\mathrm{1.5\ V}


Option: 4

\mathrm{0.5\ V}

Reverse biased potential for the zener breakdown
\mathrm{V_r=E d=10^6 \times 2.5 \times 10^{-6}=2.5 \text { volt }}
