The ZA Series of transient voltage surge suppressors are radial-lead 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: 5 mm, 7 mm, 10 mm, 14 mm and 20 mm, and feature a wide VDC voltage range of 5.5 V to 615 V.
Features:

Average Power Dissipation of Transients Not to Exceed 0.2 W, 0.25 W, 0.4 W, 0.6 W or 1 W for Model Sizes 5 mm, 7 mm, 10 mm, 14 mm, and 20 mm Respectively

ZA Series Varistors Are Listed Under UL File No. E135010 as a UL Recognized Component
