ZA Varistor Series
The ZA Series of transient voltage surge suppressors are radial-lead
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
voltage range of 5.5V to 615V.
DC
See ZA Series Device Ratings and Specifications table for part number
and brand information.

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.

Power Dissipation Ratings
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 Figure 1. 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.

NOTE: If pulse ratings are exceeded, a shift of V
(at specified current) of more then ±10% could result. This type of shift, which normally results in a decrease of V
N(DC),
N(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.

ZA series varistors for Hi-Temperature operating conditions:
• Phenolic Coated ZA Series devices are available with improved maxi-
mum operating maximum temperature 125°C.
• These devices also have improved temperature cycling performance
capability.
• To order this crimped and trimmed lead style, standard radial type
model numbers are changed by replacing the model letter “ZA” with
“ZC”. This option is supplied in bulk only.
• Ratings and Specifications are as per standard ZA Series except Hi-
Pot encapsulation Isolation Voltage Capability = 500V.
• To order: add X1347 to part number (e.g. V22ZA3X1347)
• These devices are not UL, CSA, VDE or CECC certified.
• Contact factory for further details.

For crimped leads without trimming and any varitions to the above,
contact Littelfuse.
Ordering Information
ZA series Varistors are shipped standard in bulk pack with straight leads
and lead spacing outlined in the package dimensions on page 4-13.
Contact your Littelfuse sales representative to discuss the non-standard
options outlined below.
• For 10/±1mm lead spacing on 20mm diameter models only; append stan-
dard model numbers by adding “X10”.
Example:
For Lead-free and RoHS compliant parts add the letter ‘P’ after the base
part number and before any option as shown in the ordering example
below.
