Bourns PTVS3-xxxC-TH devices offer bidirectional port protection of 380, meeting IEC 61000-4-5 8/20 μs current surge requirements. 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.
