TMOV and iTMOV Varistor Series
Description
The LittelfuseTMOV® and iTMOV® thermally protected
varistors represent a new development in integrated
circuit protection. Both versions are comprised of radial
leaded Metal Oxide Varistors (MOVs) with an integrated
thermally activated element designed to open in the
event of overheating due to the abnormal overvoltage,
limited current, conditions outlined in UL1449. TheTMOV®
and iTMOV® varistor’s integrated thermal element, in
conjunction with appropriate enclosure design, helps
facilitate SPD module compliance to UL1449 for both cord
connected and permanently connected applications.
TheTMOV® and iTMOV® varistors offer quick thermal
response due to the close proximity of the integrated
thermal element to the MOV body. The integrated
configuration also offers lower inductance than most
discrete solutions resulting in improved clamping
performance to fast overvoltage transients.

The iTMOV® varistor differs from theTMOV® varistor by the
inclusion of a third lead for the purpose of indicating that
the MOV has been disconnected from the circuit. This lead
facilitates connection to monitoring circuitry.

AdditionallyTMOV® and iTMOV® varistors are wave
solderable, thus simplifying end product assembly by
reducing the the expense and rework associated with hand
soldering operations.

Note :TheTMOV® and iTMOV® varistors are intended, in conjunction
with appropriate enclosure design, to help facilitate SPD module
compliance to UL 1449, 3rd Edition Section 39.4 (abnormal
overvoltage limited current requirements). Under these extreme
abnormal overvoltage conditions, some units will exhibit substantial
heating, arcing and venting prior to opening. Modules should be
designed to contain this possibility. Application testing is strongly
recommended.
For applications exceeding 85°C ambient temperature, the peak
surge current and energy ratings must be reduced as shown
above.

Wave Solder Profile
Because the TMOV® and iTMOV® varistors contain a thermal protection device, care must be taken when soldering the devices into place.
Two soldering methods are possible. Firstly, hand soldering: It is recommended to heat-sink the leads of the device. Secondly, wave solder-
ing: It is critically important that all preheat stage and the solder bath temperatures are rigidly controlled.

iTMOV® Varistor Application Examples
The application examples below show how the indicator lead on the iTMOV® varistor can be used to indicate that the
thermal element has been opened. This signifies that the circuit is no longer protected from transients by the MOV.
Application Example 1
Application Example 3
In this case, the LED is normally on, and is off when the
thermal element opens.
This circuit illustrates the use of the monitoring lead of
the iTMOV® varistor to ensure that equipment is only
operated when overvoltage protection present. In normal
operation the load switch relay solenoid is powered via the
indicator lead of the iTMOV® varistor. In the event of the
thermal element being activated, the relay will de-activate,
cutting power to the protected circuit and the fault LED will
illuminate.

This circuit utilizes an optocoupler to provide
galvanic isolations between the iTMOV® varistor
and the indicating or alarm circuitry.

Please note: Indicator circuits are provided as a
guideline only. Verification of actual indicator circuitry
is the responsibility of the end user. Component
values selected must be appropriate for the specific
AC line voltage service and application.
