Bourns announced two new high-power TVS (transient voltage suppression) diodes in surface mount packaging. They are designed for DC clamping in exposed AC/DC power supply applications such as wireless base stations. Designated models PTVS3-058C-SH and PTVS3-076C-SH, the devices offer bidirectional port protection meeting IEC 61000-4-5 8/20 μs current surge requirements.
According to the manufacturer, silicon technology in these devices delivers multiple advantages including lower clamping voltage under surge, greater performance stability and increased reliability compared to competing MOV technology that is typically used for DC clamping applications.
Bourns selected the SMD package for its latest Power TVS products because this type of packaging can simplify assembly and reduce manufacturing costs by eliminating the extra assembly step in situations where the diode is the only through-hole component on the printed circuit board.
These devices offer excellent surge response versus temperature, where the typical maximum surge current at 150°C exceeds 70% of their rated value at 25°C. The new models also feature standoff voltage of 58 V and 76 V with a peak pulse current rating of 3 kA.
