AVR Series Multilayer Chip Varistors

TDK’s AVR series chip varistors for ESD protection

Image of TDK's AVR Series Multilayer Chip Varistors TDK's AVR series chip varistors have excellent absorption capability with a response that is as good or better than a Zener diode. A single AVR series part can replace a Zener diode and capacitor combination, reducing the overall footprint and total mounting cost. AVR series parts have no polarity due to symmetrical current-voltage characteristics and keep this symmetrical current-voltage characteristic even after electrostatic absorption. The AVR series offers a wide range of varistor voltages (from 6.8 V to 90 V) and is available in a variety of case sizes (from 0.4 mm x 0.2 mm to 2.0 mm x 1.2 mm) for consumer and automotive applications.
