Protection of Electronic Circuits from Overvoltages
A varistor with a parasitic capacitance of 2 nF has an rms current of 0.09 mA
when installed between line and ground on mains with a nominal voltage of 120
V rms and a frequency of 60 Hz. Such a varistor has an inadequate safety margin
to ...

spike in the power supply) a large current will flow through the varistor to ground
before it can damage the circuit. To operate in this way a varistor must have a
highly nonlinear I–V relationship, as shown in Figure 30.17. At low applied
voltages ...

AC Power Systems Handbook, Third Edition
The service drop comes into the meter panel and is connected to a primary
lightning arrester and a primary varistor. The circuit shown is duplicated three
times for a three-wire wye (208 V phase-to- phase, 120 V phase-to-neutral)
power ...

The Forrest Mims Circuit Scrapbook
What is understood is that the varistor is well suited for protecting electronic
circuits from transient voltage surges. The current through a standard resistor is
directly proportional to the voltage across the resistor. The current through a
varistor, ...

DC/AC Circuits and Electronics: Principles & Applications
The varistor is still another two-terminal device. Its schematic symbol and
characteristic curve are shown in Figure 4-20. The varistor, like the diode, is
sensitive to the voltage across it. However, the varistor is designed to conduct at
a specified ...

The Circuits and Filters Handbook, Second Edition
A voltage dependent resistor (VDR), called a varistor, is a resistor whose
characteristic V versus / is not a straight line and a small change of voltage
causes a significant change of current according to the equation V = C/P (10.9)
where P is ...

Electronic Ceramics: Properties: Devices, and Applications
It should also be emphasized that an important and significant feature of the
behavior of ZnO varistors is that macroscopic breakdown voltages of 2 or 3 V /
barrier are observed for a wide variety of ZnO varistor materials. Substantial
variations ...
