Metal-Oxide Varistors
(MOVs)
Radial Lead Varistors > ZA Series
ZA Varistor Series
Description
RoHS
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 V
DC
voltage range of 5.5V to 615V.

Note:
1. Average power dissipation of transients not to exceed 0.2W, 0.25W, 0.4W, 0.6W or 1W for
model sizes 5mm, 7mm, 10mm, 14mm and 20mm, respectively.
2. Energy rating (auto load dump) for impulse duration of 40ms minimum to one half of peak
current, 60 sec interval (ISO7637-2 pulse 5a and ISO16750-2 Table 5A)
3. 10mA DC test current.
4. Also rated to withstand 24V for 5 minutes.
5. Higher voltages available, contact Littelfuse.
6. Also rated to withstand 48V for 5 minutes.
7 Energy rating for impulse duration of 30ms minimum to one half of peak current (Auto
.
Load Dump): 100J
8. The typical capacitance rating is the discrete component test result.

Current Energy and Power Dissipation Ratings
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 1A - Power Derating for Epoxy Coated
100
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.
