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. See ZA Series Device Ratings and Specifications Table for part number and brand information. Agency Approvals Agency File Number Features E135010, (+ E320116 for selected parts) 116895 42201-006

8BWFGPSN 8μs = T1 = Rise Time 20μs = T2 = Decay Time Should transients occur in rapid succession, the average power dissipation required is simply 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 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.
