Fast Response 10D 561k Metal Oxide Varistor Low Clamping Ratio And
No Following-On Current
Metal oxide varistors are key protection devices for power and
electronic systems, which directly determine the safety and
reliability of system operation. This book systematically
introduces the basic research, preparation process, performance
regulation and application progress of zinc oxide and other
varistors, including conduction and aging mechanism, microstructure
electrical characteristics, microstructure testing and
microstructure simulation analysis, research progress of
high-gradient low residual voltage oxide varistors, titanium oxide,
tin oxide and other system varistors, and establishes the
correlation between microstructure characteristics and macroscopic
characteristics of varistors relationship
Electrical properties
A piezoresistor remains non-conductive during normal operation. As
a parallel mode device, varistors are commonly used to suppress
line voltage surges when the voltage across the varistor is well
below its "clamping voltage". There are two reasons for the failure
of varistors.
As a result of unsuccessful attempts to limit very large surges
caused by events such as lightning strikes, catastrophic failures
occur in which the energy involved is many orders of magnitude
higher than the varistor can handle. The subsequent currents
generated by the impact may melt, burn or even vaporize the
varistor. This thermal runaway is due to a lack of uniformity at
individual grain boundary junctions, which causes the dominant
current path to fail under thermal stress when the energy (usually
measured in joules) of the transient pulse is too high (i.e.,
significantly above the "absolute maximum rating" manufacturer).
The potential for catastrophic failure can be reduced by
over-rating or by using specially selected MOVs in parallel.
