What do you understand by breakdown and breakdown voltage?
Asked by Topperlearning User | 18 Jun, 2014, 11:15: AM
Expert Answer
If the applied reverse voltage is increased gradually, then a stage is reached when covalent bonds in semiconductor are broken and a large number of charge carriers (electron-hole pair) are generated which give rise to a sharp increase in reverse current. This phenomenon is called breakdown .The voltage at which breakdown occurs is called breakdown voltage.
