this page was intentionally left blank. thermally protected varistors | 1 world products, llc 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 specifed rated voltage, but metal oxide varistors may fail to a short-circuit condition or fail to open when subjected to sustained steady-state over-voltage above its rated specifcations. 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, llc three-leaded device 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, llc thermally protected varistors offer protection to sensitive downstream electric components. additionally, tvz varistors are wave solderable which simplifes 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 (spds) 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 thermo 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. table of contents features .................................................................................... 2 applications ................................................................................. 2 approvals .................................................................................. 2 part marking ................................................................................ 3 part number system .......................................................................... 4 absolute maximum ratings .................................................................... 4 fuse confguration and dimensions .............................................................. 5 specifcations ............................................................................... 12 thermal characteristics & soldering profle ........................................................ 22 v-i characteristics ............................................................................ 24 taping specifcations ......................................................................... 26 standard bulk packaging ...................................................................... 28 carton size of bulk packaging .................................................................. 28 applications ................................................................................. 29 ac line application examples .................................................................. 29 t hermally p rotectected v arist ors world products inc. 19654 eighth street east, sonoma, ca 95476 | phone (707) 996-5201 | fax (707) 996-3380 | www.worldproducts.com rev. 12.3 2 | thermally protected varistors features ?
