Power dissipation of XnO-based metal oxide varistors (MOVs) for electronic circuit protection
Proceedings. 7th International Conference on Solid-State and Integrated Circuits Technology, 2004., 2005Power dissipation in the high-current (upturn) region of the current-voltage characteristic of ZnO-based metal oxide varistors (MOVs) has been observed to be influenced by the ZnO grain resistivity and nonlinearity. Power dissipation lower than 20 kW was observed in samples with lower grain resistivity values (less than 1 /spl Omega/cm) and higher ...
