Bourns, Inc. has claimed the industry’s first power transient voltage suppressors (PTVS) available in a compact DFN package, measuring 8 × 6 × 2.5 mm. The PTVS1 and PTVS2 surface-mount series provides ESD protection, delivering high surge current solutions that also save PC-board space.
The company also claims the Model PTVS2-xxxC-H series as the first PTVS device to feature the surge handling capability of 2 kA (8/20 μs). The combination of smaller packaging and higher surge protection makes the devices suited for a range of AC and DC line protection applications such as those with exposed PoE ports or that need high-power DC bus protection including 5G small cell, remote radio units (RRUs), and baseband units (BBUs) in wireless base stations.
The new Model PTVS1-xxxC-H high-current PTVS diode series consists of eight part numbers with a maximum standoff Voltage between 22 V to 86 V. The bidirectional PTVS Series is said to offer very low clamping voltage under surge conditions and excellent performance over temperature. The model PTVS1 series meets IEC 61000-4-2 Level 4 ESD protection and 1 kA (8/20 μs) per IEC 61000-4-5 lightning protection.
The PTVS2-xxxC-H PTVS diode family is offered in eight part numbers with a maximum standoff voltage between 22 V and 86 V. It offers surge handling capability of 2 kA (8/20 μs) per IEC 61000-4-5 lightning protection. This series meets IEC 6100-4-2 Level 4 ESD protection.
The Model PTVS1-xxxC-H and PTVS2-xxxC-H PTVS diode series are available now. The devices are Rohs compliant and halogen free.
