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.

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 for impulse duration of 30ms minimum to one half of peak current (auto Load Dump).
3. 10mA DC test current.
4. Also rated to withstand 24V for 5 minutes.
5. Higher voltages available, contact Littelfuse.
6. Capacitance Values shown areTYPICAL.

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 SpecificationsTable 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.
01 = Virtual Origin of Wave
T =Time from 10% to 90% of Peak
T1 = RiseTime = 1.25 xT
T2 = DecayTime
Example - For an 8/20 μs Current Waveform:
8μs =T1 = RiseTime
20μs =T2 = DecayTime

NOTE: If pulse ratings are exceeded, a shift of VN(DC)(at specified current) of more then +/-10% could result. This type of shift, which normally results
in a decrease of VN(DC), may result in the device not meeting the original published specifications, but does not prevent the device from continuing to
function, and to provide ample protection.
