The PTVS3-015C-TH device is part of Bourn’s recently extended range of PTVS3 series high current TVS Diodes and is claimed to offer surge current protection of 3kA at 25°C. Typical target applications are exposed AC/DC power supplies, for example in wireless base stations.
The PTVS3 series also offers bidirectional port protection meeting IEC 61000-4-5 8/20µs current surge requirements and is RoHS compliant and halogen free.
When compared to typical competing MOV technology, the use of silicon technology in the Power TVS products is said to provide a lower clamping voltage under surge, greater performance stability and increased reliability.
These devices exhibit an excellent surge response versus temperature; the maximum surge current at 150°C exceeds 70% of their rated value at 25°C.
