Bourns, Inc. announced a significant expansion of the company’s high voltage Power Transient Voltage Suppressor (PTVS) product line. Offering superior bidirectional port protection from 170 volts to 430 volts, the nine new PTVS devices are designed to meet stringent IEC 61000-4-5 8/20 µs current surge requirements in a broad variety of AC line and high-power DC clamping applications such as those in exposed AC/DC power supplies in outdoor environments. An advantage for customers is that PTVS silicon-based technology delivers lower clamping voltage under surge, greater performance stability and increased reliability compared to the capabilities offered from typical competing MOV technology.
The Bourns® PTVS products also offer an excellent surge response versus temperature; the typical maximum surge current at 150 °C exceeds 70 % of their rated value at 25 °C.
The new Bourns® PTVS products are RoHS compliant* and available now. As a pricing reference, the Bourns® Model PTVS6-430C-TH is priced at $ 72.60 each in 10 piece quantities.
