Metal-Oxide Varistors (MOVs) 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, 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 V voltage range of 5.5V to 615V. DC See ZA Series Device Ratings and Specifications Table for part number and brand information.
