The Models PTVS6-058C-TH and PTVS6-076C-TH power transient-voltage suppression (TVS) diodes provide high current bidirectional port protection that meets IEC 61000-4-5 8/20 µs current surge requirements. They offer a lower clamping voltage under surge compared to metal oxide varistor (MOV) technology and a typical maximum surge current at 150°C is 75% of their rated value at 25°C. Both models provide a peak pulse current rating of 6 kA. The Model PTVS6-058C-TH features a 58V standoff voltage and the model PTVS6-076C-TH has a 76 V standoff voltage. Price for either model is $12.60 each/500. To peruse a datasheet, go to http://www.bourns.com/data/global/pdfs/PTVS6-TH.pdf.
