Housed in a SOD523 (SC79) package measuring 0.8-by-1.6-by-0.6 mm, the new ESD protection diode series from Vishay Intertechnology Inc. is optimized for space-critical applications.

Intended to provide ESD protection for data lines in mobile phone handsets and accessories, cordless phones, laptop computers, PDAs, digital cameras, modems, MP3 players and other compact, handheld electronics, the VESDxx-02V series offers one-line transient protection of 15kV (air) and 8kV (contact) as per IEC 61000-4-2.

In addition to meeting the industry standard for ESD protection required by mobile phone manufacturers, this series also saves space compared to multi-line arrays while giving designers the flexibility to add protection for sensitive electronics on compact circuit boards exactly where it is needed, Vishay said.

The diode series offers designers a choice of five working voltage values ranging from 1V to 12V, and maximum clamping voltages from 9V to 25V. Low leakage current helps to prolong battery life, the company added.

Specified for operation between the -40C and 125C temperature range, the five newly-released devices are packaged in a plastic case with a UL 94 V-0 flammability rating. Samples and production quantities of the new VESDxx-02V diodes are already available with lead times of 8 to 12 weeks for larger orders. These products are available for delivery in tape-and-reel packaging.
