World Products Inc. TVZ series is a two or three-leaded
Thermally Protected Metal Oxide Varistor
One lead of the TVZ varistor is connected to a thermal link which is designed to open when the varistor is under sustained
abnormal over-voltage conditions. The TVZ series is designed to meet the abnormal over-voltage requirements of UL 1449 3rd
edition, Section 39.4.
Traditional Metal Oxide Varistors were originally designed to protect equipment from surges at the specified rated voltage, but
Metal Oxide Varistors may fail to a short-circuit condition or fail to open when subjected to a sustained steady-state overvoltage
above it’s rated specification. The TVZ has a thermal link integrated with an MOV disk that responds to the MOV temperature and
disconnects the MOV from the line, should the temperature or voltage exceed a certain level.
World Products Inc. three-leaded surge protective component is designed to be connected, via the monitor lead, to an indicator
(such as an LED) to provide diagnostic features indicating if the MOV is disconnected from the circuit in the event the thermal link
element opens.
As a result of the integration of the thermal link attached to the MOV disc, Thermally Protected Varistors provide an instant
response to unexpected over-voltage situations. World Products Inc. Thermally Protected Varistors offer protection to sensitive
downstream electric components.
Additionally, TVZ varistors are wave solderable which simplifies end product assembly by reducing the expense and rework
associated with hand soldering operations.
CAUTION: Thermally Protected Varistors are intended, in conjunction with appropriate enclosure design, to help facilitate
SPD module compliance to UL 1449. Under extreme abnormal over-voltage conditions, some units will exhibit substantial
heating, arcing and venting prior to opening. Modules must be designed to contain this possibility. Application testing is strongly
recommended.
Proper design of surge protective devices (SPD’s) require that they meet new UL1449 3rd Edition requirements for
abnormal over-voltage limited current. Fuses that are meant to protect the system for large fault currents do not address
the need to protect against low fault currents. These low fault currents can result in catastrophic failure prior to tripping
the higher current fuse. TVZ series varistors can meet the needs of the SPD designer, avoiding having to create a
complicated/high cost approach.
The thermal link in a thermally protected varistor should never be used in series with the load. It is only used to provide
protection to the varistor portion in case of an abnormal over voltage condition.
When considering “potting materials” being used in conjunction with TVZ, please contact World Products Inc. for
guidelines as “potting” may affect TVZ performance characteristics.

Rev. 12.8
Thermally Protectected Varistors
Thermal Characteristics & Soldering Profile (continued)
Wave Solder Profile
Because TVZ varistors contain a thermal protection device,
care must be taken when soldering the devices into place.
Two soldering methods are possible. First, hand soldering:
It is recommended to heat-sink the leads of the device. Second,
wave-soldering: It is critically important that all preheat stage and
the solder bath temperatures are rigidly controlled.

At idle power, current levels shown to the left of the discontinuity illustrate typically the high end leakage current. However, if lower leakage current levels are
desired, they may be guaranteed. in the clamping voltage region to the right of the discontinuity, maximum clamping voltage is plotted. WORLD PRODUCTS INC. 19654 Eighth Street East, Sonoma, CA 95476 | Phone (707) 996-5201 | Fax (707) 996-3380 | www.worldproducts.com

Thermally Protectected Varistors
AC Line Application Examples
Thermally Protected Varistors are surge protective components (SPC’s). The configurations available are either a two
or three leaded component. One lead is connected to a thermal link, which may open when the varistor is subjected to
prolonged over-voltage conditions in both AC and DC applications, thereby preventing failure mode of the varistor. This
component (in the three leaded configuration) further provides for diagnostic capabilities in the customers circuit.
