TMOV(R) and iTMOV(R) Varistor Series
The Littelfuse TMOV and iTMOV thermally protected varistors represent a new development in integrated circuit protection (patent pending). Both versions are comprised of radial leaded MOVs (Metal Oxide Varistors) with an integrated thermally activated element designed to open in the event of overheating due to the abnormal over-voltage, limited current, conditions outlined in UL1449. The iTMOV varistor differs from the TMOV 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. The TMOV 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 over-voltage transients. Additionally, TMOV and iTMOV varistors are wave solderable, thus simplifying end product assembly by reducing the expense and rework associated with hand soldering operations. The TMOV and iTMOV varistors are both recognized surge suppression components to UL 1449. The TMOV and iTMOV varistor's integrated thermal element, in conjunction with appropriate enclosure design, helps facilitate TVSS module compliance to UL1449 for both cord connected and permanently connected applications. TMOV and iTMOV varistors are compatible for use with industry standard wave-soldering processes or recommended hand-soldering methods.

iTMOV Varistor Application Examples
The application examples below show how the indicator lead on the iTMOV 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 2 (Figure 2)
This circuit utilizes an optocoupler to provide galvanic isolations between the iTMOV varistor and the indicating or alarm circuitry.
Application Example 3 (Figure 3)
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.

Note : The TMOV and iTMOV varistors are intended, in conjunction with appropriate enclosure design, to help facilitate TVSS module compliance to UL 1449, Section 37.4 (abnormal over-voltage limited current requirements). Under these extreme abnormal over-voltage conditions, the units will exhibit substantial heating and potential venting prior to opening. Modules should be designed to contain this possibility. Application testing is strongly recommended.
For applications exceeding 85C ambient temperature, the peak surge current and energy ratings must be reduced as shown in Figure 3.

Soldering Recommendations
Because the TMOV and i TMOV 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-soldering: It is critically important that all preheat stage and the solder bath temperatures are rigidly controlled. The recommended solder for the TMOV and i TMOV varistors is a 62/36/2 (Sn/Pb/Ag), 60/40 (Sn/Pb) or 63/37(Sn/Pb). Littelfuse also recommends an RMA solder flux.
