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, 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.

Current Energy and Power Dissipation Ratings
device. 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
