Edited by the Electronicstalk editorial team Jun 29, 2010

NXP Semiconductors has extended its transient voltage suppressor (TVS) diodes portfolio designed to protect sensitive components against transient voltages in industrial and automotive applications.

The range has been extended by 35 products housed in the company's two-lead Flatpower package SOD128 (3.8 x 2.5 x 1mm).

NXP said it is the first supplier to offer a 600W peak pulse power rating (10/1000us) TVS diode in such a small plastic SMD package.

The SOD128 Flatpower package fits on a SMB footprint allowing a 1:1 replacement and enabling engineers to save space on the PCB while delivering optimum power performance.

The TVS diodes are designed to protect sensitive components against transient voltages in various electronic applications such as power management units and telecommunication circuits.

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

Due to the very low leakage current of 1nA (typical) the PTVS series reduces energy consumption and facilitates its use in battery-powered mobile applications.

The low height and small outline dimensions save PCB space and allow further miniaturisation of circuit designs.

The 600W product family PTVS*P1UP offers 35 stand-off voltages from 3.3V to 64V.

It extends NXP's 400W TVS product family PTVS*S1UR that is housed in the smaller Flatpower package SOD123W with an outline of 2.6 x 1.7 x 1.0 mm.

SOD128 and SOD123W are free of halogens and antimony oxides and comply with non-flammability classification UL94 V-0 and RoHS standards.
