The breakdown voltage of an insulator is the minimum voltage that causes a portion of an insulator to become electrically conductive. For diodes, the breakdown voltage is the minimum reverse voltage that makes the diode conduct appreciably in reverse.

WebIt is illustrated by the E (d) dependence in atmospheric air, presented in Fig. 2. The bigger gap and the bigger avalanche we have, the less sensitive is the reduced electric field E/p to the ... WebWhen breakdown occurs, the present electric field frees the electrons. If the electric field is strong enough, the freed electrons may accelerate and liberate other electrons when they collide with neutral atoms or molecules. The liberation of electrons may turn the material into a conductor with its positive charge.
