Metal-Oxide Varistors (MOVs) Radial Lead Varistors > ZA Series 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, 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.

The operating values of a MOV need to be derated at high temperatures as shown above. Because varistors only dissipate a relatively small amount of average power they are not suitable for repetitive applications that involve substantial amounts of average power dissipation. Should transients occur in rapid succession, the average power dissipation is the energy (watt-seconds) per pulse times the number of pulses per second. The power so developed must be within the specifications shown on the Device Ratings and Specifications Table for the specific Figure 1B - Power Derating for Phenolic Coated 100 100 90 90 PERCENT OF RATED VALUE PERCENT OF RATED VALUE Figure 1A - Power Derating for Epoxy Coated 80 70 60 50 40 30 20 80 70 60 50 40 30 20 10 10 0 -55 50 60 70 80 90 100 110 120 AMBIENT TEMPERATURE ( oC) 130 0 -55 140 150 70 80 90 100 110 100 01 = Virtual Origin of Wave T = Time from 10% to 90% of Peak T1 = Rise Time = 1.25 x T T2 = Decay Time Example - For an 8/20 µs Current Waveform: 8µs = T1 = Rise Time 20µs = T2 = Decay Time 90 50 10 O1 T T1 TIME T2 O = Virtual Origin of Wave 1 © 2018 Littelfuse, Inc.
