TVS Diodes Handle High-Power Line Apps
January 29, 2014
Bourns’ latest high Power TVS diode models in SMD packaging are suitable for use in ac and dc power line applications. They feature high current bidirectional port protection meeting IEC 61000-4-5 8/20 µs current surge requirements and are RoHS compliant. The Models PTVS15-058C-SH and PTVS15-076C-SH deliver lower clamping voltage under surge compared to Metal Oxide Varistor (MOV) technology and their SMD packages provide a 20% reduction in peak clamping voltage compared to an equivalent through-hole device because of its lower lead inductance. Both models feature a maximum surge current rating at +150°C and a peak pulse current rating of 15 kA. The Model PTVS15-058C-SH features a 58V standoff voltage and the PTVS15-076C-SH has a 76V standoff voltage. As a pricing reference, the PTVS15-058C-SH and PTVS15-076C-SH are priced at $19.70 each/10 and $17.50 each/500. A datasheet is available at http://www.bourns.com/data/global/pdfs/PTVS15-SH.pdf.
