Transient voltage suppressor diodes save PCB space

Offering a 400W peak pulse power rating (10/1000us), the diodes dissipate approximately 67W/mm2 surge per PCB area.

Such high surge capabilities over smaller areas will enable engineers to save space on the PCB while delivering optimum power performance.

It will also allow engineers to integrate more functions on the PCB.

The TVS diodes are designed to protect voltage-sensitive components against transient voltage in various electronic applications such as power supplies, data or signal lines, medical equipment, and telecommunication circuits.

Qualified to the rigorous AEC-Q101 standard, the Flatpower TVS devices can be used for all automotive and industrial applications.

With its very low leakage current of 1nA and small size, the SOD123W TVS device can also be used in battery-driven products where space is a constraint.

With a height of 1mm and overall size of 2.6mm x 1.7mm x 1mm, the SOD123W occupies only half the PCB area when compared to competitive TVS diodes in SMA packages, said NXP.

The Flatpower SOD123W package fits on an SMA footprint, providing a suitable solution for a 1:1 replacement.

The first 18 parts of the product range come with stand-off voltages from 3.3V to 18V and an additional 17 types with stand-off voltages up to 64V will be released mid-2009 to complete the portfolio.

The SOD123W meets environmental protection targets.

The plastic is free of halogens and antimony oxides and complies with non-flammability classification UL 94V-0 and RoHS standards.
