New from Bourns are the PTVS3-xxxC-TH high-current bidirectional transient voltage suppression (TVS) diodes designed for use in high-power DC bus clamping applications. They offer bidirectional port protection meeting IEC 61000-4-5 8/20 s current surge requirements and are RoHS compliant.
When compared to competing MOV technology, the use of silicon technology in these devices provides a lower clamping voltage under surge, greater performance stability and increased reliability. Compared to the already released Bourns PTVS3-xxxC high current TVS diodes, these new parts exhibit excellent surge response versus temperature; the typical maximum surge current at 150°C is 75% of their rated value at 25°C.
