Transient Voltage Suppression Diodes ATTENTION Usage 1. TVS must be operated in the specified ambient temp. 2. Do not clean the TVS with strong polar solvent such as ketone, esters, benzene and halogenated hydrocarbon, to avoid damaging the encapsulating layer. 3. Please do not apply severe vibration, shock or pressure to TVS, to avoid element cracking. 1. If TVS is visually damaged, please replace it. 2. TVS is a non-repairable product. For safety sake, please use equivalent TVS for replacement. 1. Storage Temp. Range: (-55 to 150) °C. 2. Do not store the TVS at the high temp., high humidity...
