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 application, low voltage power
conversion circuits and power supervisory chip sets. In
addition, 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 packages (0405 and 0508), and
4-element packages (0612).
