| Varistor Products Radial Lead Varistors > ZA Series RoHS ZA Varistor Series Description The ZA Series of transient voltage surge suppressors are radial leaded varistors (MOVs) designed for use in the protection of low and medium-voltage 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. Agency Approvals Agency Agency File Number See ZA Series Device Ratings and Specifications Table for part number and brand information.

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 the diagram above. 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.
