AVX Multilayer Ceramic Transient Voltage Suppressors
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.
