Bourns Power TVS Diode for High Power DC Bus Protection
Next-generation power TVS diodes that achieve high surge tolerance and low clamp voltage.
Bourns has expanded its lineup of high-current bidirectional TVS diodes with the "PTVS3-0xxxC-TH series." The newly added "PTVS3-066C-TH" is a 66V product that extends the operating voltage (standoff voltage) range of the series. This product is a high-surge capacity TVS diode designed for high-power DC bus circuits, providing excellent overvoltage protection performance. It complies with RoHS directives and meets the 8/20μs surge test requirements of IEC 61000-4-5 standards. The Bourns Power TVS (PTVS) series was developed for AC line protection and high-power DC bus clamping applications. It supports a wide range of standoff voltages from 58V to 470V, enabling transient overvoltage protection for bidirectional ports. Since the Power TVS series employs silicon technology, it can maintain lower clamp voltages during surge application compared to traditional MOVs (metal oxide varistors). This reduces stress on the protected circuit and contributes to improved system reliability.
