UltraGuard Series
ESD Protection for Low Leakage Requirements
GENERAL DESCRIPTION
Faster semiconductor clock speeds and an increasing reliance on batteries as power
sources have resulted in the need for varistors that exhibit very low leakage current.
The UltraGuard (UG) Series of AVX Transient Voltage Suppressors address this
problem.
The UG Series is the ideal transient protection solution for high clock speed integrated
circuit application, battery-operated device, backlit display, medical/instrument applica-
tion, low voltage power conversion circuits and power supervisory chip sets. In addi-
tion, UltraGuard’s low leakage characteristics are also suitable for optic circuits like
LDD, SerDes, and laser diodes.
The UG Series is offered as discrete chips (0402, 0603, and 0805), 2-element pack-
ages (0405 and 0508), and 4-element packages (0612).
