Varistor Products Low to Medum Voltage, Radial Lead RoHS Pb ZA Varistor Series D V E ® The ZA Series of transient voltage surge suppressors are radial-lead varistors (MOVs) designed for use in the protection of low and mediumvoltage circuits and systems. Typical applications include motor control, telecom, automotive systems, solenoid, and power supply circuits to protect circuit board components and maintain data integrity. These devices are available in five model sizes: 5mm, 7mm, 10mm, 14mm and 20mm, and feature a wide VDC voltage range of 5.5V to 615V. See ZA Series Device Ratings and Specifications table for part number and brand information. 2 Features VARISTOR PRODUCTS • Lead-free and RoHS compliant option available.

The power so developed must be within the specifications shown on the Device Ratings and Specifications table for the specific device. Furthermore, the operating values need to be derated at high temperatures as shown in Figure 1. Because varistors can only dissipate a relatively small amount of average power they are, therefore, not suitable for repetitive applications that involve substantial amounts of average power dissipation. 80 70 60 50 40 30 2 20 0 -55 50 60 70 80 90 100 110 120 130 140 VARISTOR PRODUCTS 10 150 AMBIENT TEMPERATURE ( oC) PERCENT OF PEAK VALUE FIGURE 1.

ZA series varistors for Hi-Temperature operating conditions: • To order this crimped and trimmed lead style, standard radial type model numbers are changed by replacing the model letter “ZA” with “ZC”. This option is supplied in bulk only. Example: STANDARD CATALOG MODEL ORDER AS: V18ZA3 V18ZC3 For crimped leads without trimming and any varitions to the above, contact Littelfuse. • For 10/±1mm lead spacing on 20mm diameter models only; append standard model numbers by adding “X10”.
