TransGuard®
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. This
does not mean that TransGuard suppressors do not suffer
degradation, but it occurs at much higher current.

TYPICAL PERFORMANCE CURVES (0603, 0805, 1206 & 1210 CHIP SIZES)
VOLTAGE/CURRENT CHARACTERISTICS
Multilayer construction and improved grain structure result in excellent transient clamping characteristics up to 500 amps peak
current, depending on case size and energy rating, while maintaining very low leakage currents under DC operating condi-
tions. The VI curve below shows the voltage/current characteristics for the 3.3V, 5.6V, 12V, 14V, 18V, 26V, 30V, 48V and
60VDC parts with currents ranging from parts of a micro amp to tens of amps.

PULSE DEGRADATION
Traditionally varistors have suffered degradation of electrical perfor-
mance with repeated high current pulses resulting in decreased
breakdown voltage and increased leakage current. 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
both 5.6 and 14V TransGuard transient 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. The plots
of typical breakdown voltage vs number of 150A pulses are
shown below.
