The ZVX Series SMD varistor from Stackpole (Raleigh, NC) is a great choice for fast response transient voltage suppression due to its low capacitance. Lower capacitance is required to eliminate possible distortion of data signals due to capacitive loading. Stackpole and Keko Varicon offer ZVX SMD Series of varistors in 0603, 0805 and 1206 case sizes. Applications include suppression of inductive switching, protection for high-speed data lines, and ESD protection for sensitive semiconductor components. Features include:

• Typical capacitance of 80pF to 200pF for size 0603.
• Typical capacitance of 100pF to 500pF for size 0805.
• Typical capacitance of 165pF to 840pF for size 1206.
• Working voltages from 2 to 30Vrms and 3.3Vdc to 38Vdc.
