StaticGuard
AVX Multilayer Ceramic Transient Voltage Suppressors
ESD Protection for CMOS, Bi Polar and SiGe Based Systems
GENERAL DESCRIPTION
The StaticGuard Series are low capacitance versions of the
TransGuard and are designed for general ESD protection of
CMOS, Bi-Polar, and SiGe based systems. The low capacitance
makes these products suitable for use in high speed data trans-
mission lines.

• Working Voltage: ≤ 18Vdc
• Case Size: 0402, 0603, 0805, 1206
APPLICATIONS
•Sensors
• CMOS
• SIGe based systems
• Higher speeed data lines
• Capacitance sensitive applications
and more
FEATURES
• Typical ESD failure voltage for CMOS
and/or Bi Polar is ≥ 200V
• Low capacitance (<200pF) is
required for high-speed data
transmission.
• Low leakage current (IL) is necessary
for battery operated equipment.
• 15kV ESD pulse (air discharge) per
IEC 61000-4-2, Level 4, generates
< 20 millijoules of energy.

StaticGuard
AVX Multilayer Ceramic Transient Voltage Suppressors
Multilayer construction and improved grain structure result in
excellent transient clamping characteristics up to 20 amps
peak current, while maintaining very low leakage currents
under DC operating conditions. The VI curves below show the
voltage/current characteristics for the 5.6V, 9V, 14V, 18V and
low capacitance StaticGuard parts with currents ranging from
parts of a micro amp to tens of amps.
Traditionally varistors have suffered degradation of electrical
performance with repeated high current pulses resulting in
decreased breakdown voltage and increased leakage cur-
rent. It has been suggested that irregular intergranular
boundaries and bulk material result in restricted current
paths and other non-Schottky barrier paralleled conduction
paths in the ceramic. Repeated pulsing of TransGuard®tran-
sient voltage suppressors with 150Amp peak 8 x 20µS
waveforms shows negligible degradation in breakdown
voltage and minimal increases in leakage current.
