Abnormal Overvoltage Limited Current Test
Note : The Industrial TMOV Series TMOV34S devices are intended, in
conjunction with appropriate enclosure design, to help facilitate TVSS
module compliance to UL 1449, Section 37.4 (abnormal over-voltage lim-
ited 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.
