TDK AVR-M Chip Varistors

TDK AVR-M Chip Varistors have no polarity, due to symmetrical current-voltage characteristics that are equivalent to Zener diodes. The AVR-M Varistors offer exceptional electrostatic absorption capability and are able to maintain symmetrical current-voltage characteristics even after electrostatic absorption. A wide 6.8V to 90V range of voltages are available with capacitances as low as 1.1pF.

Features

  • No polarity, due to symmetrical current-voltage characteristics, equivalent to anode common type Zener diodes
  • Excellent electrostatic absorption capability, the response is as good or better than Zener diode, keeps symmetrical current-voltage characteristics even after electrostatic absorption
  • Inner electrode lamination structure
  • Wide range of varistor voltages available (6.8V to 90V)
  • Low capacitances from 1.1pF
  • 0402, 0603, 1005, 1608, 2012 chip sizes available
  • Excellent mount reliability
  • Good for Pb-free soldering
  • Ni/Sn electroplating
  • Good solderability and solder heat resistance
  • Can replace a Zener diode + capacitor combination to reduce footprint and the total mounting cost

Applications

  • Electrostatic absorption
  • Pulse noise absorption
