Amotech introduces their chip varistor product line. These suppressors are ZnO based devices and are designed to protect sensitive electronics equipment against high voltage transient surges in the low and medium voltage regions. The chip varistors have nonlinear voltage-current characteristics similar to back-to-back zener diodes and their multiplayer structure provide many advantages to zener diodes. The varistor breakdown voltage can range from 4 V to 470 V, which is their maximum. Surge current for the product line can range from 20 A to 400 A, capacitance value can range from 90 pF to 7.5 nF and their size can range from 0402 to 3225. Applications for these chip varistors include: LCD protection, sensor protection, I/O port protection, and interface card protection.
