(2 & 4 Elements)
AVX Multilayer Ceramic
Transient Voltage Suppression Arrays
ESD Protection for CMOS and Bi Polar Systems
TYPICAL PERFORMANCE CURVES –
VOLTAGE/CURRENT CHARACTERISTICS
Multilayer construction and improved grain structure result in
excellent transient clamping characteristics in excess of 30
amps (20 amps on MG064L18X500) peak current while
maintaining very low leakage currents under DC operating

characteristics for the 5.6V, 9V, 14V and 18V parts with cur-
rents ranging from fractions of a micro amp to tens of amps.
