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 KYOCERA 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® has low
leakage characteristics that are also suitable for optic circuits like LDD, SerDes, and laser diodes.
