Answer Posted / keshav bansal
zener breakdown is occur in thin junction which is heavily
doped.when there is an increase in reverse current there is
a strong electric field which is due to the electrons come
across the junction and enough to exert the force on
covalent bonds than there is a inc in electrons&holes pair
are produced which inc the zener current or reverse
saturation current which is independent of applied voltage.
