What do you mean by zener breakdown and avalanche breakdown?
Answer Posted / navdeep
zener breakdown occurs under the influence of strong
electric field.By the strong E.F,more breakage of covalent
bonds take place.Due to which more e-hole pairs come to
play. Then the reverse current rises abruptly and
breaakdown takes place known as zener breakdown.
Under the low influence of electric field in the
junction,the covalent bonds break and more charge carriers
are formed.and under the more reverse voltage,the reverse
current flows and the breakdown due to ore voltage is known
as avlanche breakdown.
