TVS diodes with a 400W peak pulse power rating in smaller package

NXP Semiconductor launched a new range of transient voltage suppressor (TVS) diodes housed in its new FlatPower package, SOD123W. Offering a 400 W peak pulse power rating (10/1000µs), the new diodes dissipate approximately 67 W/mm2 surge per PCB area.

The new TVS diodes are designed to suppress unexpected voltage transients in various electronic applications like power supplies, data or signal lines, medical equipments, and telecommunication circuits. Qualified to the AEC-Q101 standard, the new devices are targeted at automotive and industrial applications.

Some of the advantages and features include:

1. Because of its low leakage current of 1 nA and small size, the SOD123W device can also be used in battery driven products like mobile phones and notebooks where space is a constraint.
2. The first 18 parts of the product family come with stand-off voltages from 3.3 V to 18 V and an additional 17 types with stand-off voltages up to 64 V will be released in mid 2009 to complete the portfolio.
3. The device 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.
4. The FlatPower packages SOD123W and SOD128 (3.8 x 2.6 x 1 mm) combine high power ratings with a low profile height.

Package: SMA
Size: (2.6mm x 1.7mm x 1 mm)
Availability:
1. NXP's new TVS diodes are released and ready for production.
2. Samples are available immediately for design-in.

Price: The price ranges from $0.08 to 0.10 (USD) per piece.
