POWER TVS PRODUCTS Bourns Releases New High Power TVS Diodes with Enhanced Temperature Performance Model PTVS3-058C-TH and PTVS3-076C-TH Riverside, California - March 28, 2014 - Bourns is pleased to announce the release of the Model PTVS3-xxxC-TH Series high current bidirectional TVS diodes designed for use in high power DC bus clamping applications. These devices offer bidirectional port protection meeting IEC 61000-4-5 8/20 µs current surge requirements and are RoHS compliant*. When compared to competing MOV technology, the use of silicon technology in the Power TVS products provides a lower clamping voltage under surge, greater performance stability and increased reliability. Compared to the already released Bourns® Model PTVS3-xxxC high current TVS diodes, these devices exhibit an excellent surge response versus temperature; the typical maximum surge current at 150 °C is 75 % their rated value at 25 °C. The product data sheet with detailed specifications can be viewed on the Bourns website at www.bourns. com.
