Power TVS (PTVS) Products
Model PTVS10-170C-TH, PTVS10-320C-TH, PTVS10-380C-TH,
PTVS10-430C-TH, PTVS10-470C-TH
Riverside, California - December 16, 2014 - Bourns is pleased to announce the release of high voltage bidirectional
high current TVS diodes, Models PTVS10-170C-TH, PTVS10-320C-TH, PTVS10-380C-TH, PTVS10-430C-TH,
and PTVS10-470C-TH, designed for use in AC line and high power DC bus clamping applications.
These devices offer bidirectional port protection of 170 volts to 470 volts, 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.
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.
