StaticGuard
AVX Multilayer Ceramic Transient Voltage Suppressors
ESD Protection for CMOS, Bi Polar and SiGe Based Systems
GENERAL INFORMATION
• Typical ESD failure voltage for CMOS and/or Bi Polar
is ≥ 200V.
• Low capacitance (<200pF) is required for high-speed
data transmission.
• 15kV ESD pulse (air discharge) per IEC 1000-4-2,
Level 4, generates < 20 millijoules of energy.
• Low leakage current (IL) is necessary for battery
operated equipment.

TYPICAL PERFORMANCE CURVES (0402 CHIP SIZE)
VOLTAGE/CURRENT CHARACTERISTICS PULSE DEGRADATION
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. This
®
does not mean that TransGuard suppressors do not suffer
degradation, but it occurs at much higher current.
