Photoluminescence Study of ZnO Varistor Stability

Journal of Electronic Materials, 1995
Photoluminescence (PL) measurements were carried out on commercial ZnO varistor samples that were electrically stressed and/or annealed at different temperatures. Changes in the intensity of green and yellow luminescence centers were studied as a function of annealing treatment.

Degradation phenomena of ZnO varistors

Physica Status Solidi (a), 1981
The dc degradation behaviour of ZnO varistors as a function of the variables current, temperature, and time is investigated. The degradation rate is phenomenologically presented by an equation reflecting the observed aging behaviour in dependence on the influencing variables.

Origin of ZnO Varistor

Journal of the American Ceramic Society, 1987
The varistor properties were examined in porous ZnO. The sample used contained no dopants such as Bi 2 O 3 or Pr 6 O 11 , which are usually considered to be useful in ...

Failure modelling for ZnO varistors

Journal of Materials Processing Technology, 1998
Abstract The energy-absorption capability of zinc oxide varistors depends on both the binder burn-out and shrinkage rate of the disc. This paper presents a study of the development of a failure model of a varistor disc with a nominal voltage V nom =5 kV and a diameter of 42 mm manufactured by rate-controlled sintering.

Synthesis and characterization of multilayered ZnO/glass/ZnO varistors

AIP Conference Proceedings, 2020
Low-voltage surge filters are technologically important for the protection of modern computing and telecommunication systems operating at low voltages. In this context the design and characterization of varistors operating at low voltages constitutes a continuous challenge.

Conduction mechanisms in ZnO varistors

Journal of Applied Physics, 1980
The thermionic emission enhanced by barrier lowering and the Zener tunnelling in ZnO varistors are discussed. Capacitance versus voltage, reverse current versus temperature, and 1/f noise measurements have been performed on commercial varistors. A model is proposed from which follows a diffusion voltage VD which is consistent both with the 1/C2 vs V ...
