TVS diodes boost transient protection per PCB area

The PTVSxxxS1UR series of 400W Transient Voltage Suppression (TVS) diodes from NXP Semiconductors consume less than half the PCB area of alternatives in the industry-standard SMA package.

Using NXP’s FlatPower package technology the diodes provide 64W/mm2 of surge protection, which is more than double that of a comparable SMA device. At the same time their SOD123W outline matches the standard SMA pad layout, thereby combining space savings with the convenience of a drop-in replacement. The package fits inside the board area normally filled by an SMA device, and its mounted height of 1mm is around 50% lower.

With low leakage current of 1nA the devices serve applications requiring high energy efficiency, especially battery-powered products.

The PTVSxxxS1UR TVS diodes are available with reverse stand-off voltages ranging from 3.3V to 18V. Additional devices with stand-off voltages up to 64V will be introduced during this year. The devices are also qualified to AECQ100 allowing use in automotive and industrial systems.
