Transient Voltage Suppressors exhibit low leakage current.
March 31, 2009 -
With low leakage current of 2 µA, Zinc Oxide-based UltraGuard Series features non-linear, bi-directional voltage current characteristics and EMC capacitor in parallel. Available in models from 40-3,000 pF, multilayer ceramic varistors are suited for high clock-speed ICs, battery-operated devices, backlit displays, and power supervisory chip sets. Series comes in 0402, 0603, and 0805 sizes as well as 2-element packages in 0405 and 0508 sizes, and 4-element 0612 packages.

ZNO Based Transient Voltage Suppressor Series from AVX Exhibits Ultra Low Leakage Current
MYRTLE BEACH, S.C. (March 25, 2009) - AVX Corporation, a leading manufacturer of
advanced passive components and interconnect solutions, has developed a Zinc Oxide based varistor series that exhibits a low leakage current of 2µA maximum. Designated the UltraGuard Series, the multilayer ceramic varistors feature non-linear, bi-directional voltagecurrent characteristics similar to back-to-back zener diodes and an EMC (electromagnetic compatibility) capacitor in parallel.
"Our UltraGuard Varistor Series offers many electrical advantages over zener diodes,
including better repetitive strike capability, higher in rush current capability, faster turn-ontime, and inherent EMI/RFI attenuation," said Sonja Brown, "Furthermore, the varistors are significantly smaller, saving important board space."
The UltraGuard Series comes in discrete chips available in 0402, 0603, and 0805
sizes; 2-element packages in 0405 and 0508 sizes; and 4-element 0612 packages. Low and
high capacitance versions are offered ranging from 40 through to 3000 pF.
The varistor series is ideal for transient protection applications where power
consumption is a primary concern. These include high clock-speed ICs, battery-operated
devices, backlit displays, medical and instrumentation applications, low voltage power
conversion circuits and power supervisory chip sets. Further applications are also being found in optics such as laser diodes, laser diode drivers, and serializer and deserializer devices.
Pricing typically starts at $0.11 each in quantities of 10k.
