1 ZA Varistor Series RoHS 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: mm, 7mm, mm, 4mm and mm, and feature a wide V D voltage range of.v to 6V.
