POWER TVS PRODUCTS Bourns Releases New High Power TVS Diodes in SMD Package Model PTVS3-058C-SH and PTVS3-076C-SH Riverside, California - July 7, 2014 - Bourns is pleased to announce the release of Models PTVS3-058C-SH and PTVS3-076C-SH 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 typical 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. The SMD package should simplify assembly and costs can be reduced by eliminating the extra design step in cases where the Power TVS Diode is the only through-hole component on the printed circuit board. These devices exhibit an excellent surge response versus temperature; the typical maximum surge current at 150 °C exceeds 70 % of their rated value at 25 °C. . Bourns® Model Standoff Voltage PTVS3-058C-SH PTVS3-076C-SH 58 V 76 V Peak Pulse Current Rating (Ippm) 3 kA 3 kA Package Type SMD SMD The application note on surface mount Power TVS diodes has been updated with this new model information and the product data sheet with detailed specifications can be viewed on the Bourns website at www.bourns.com.
