Malvern, Pa. Extending the company's line of ultra-small LLP-packaged products optimized for data-line protection in compact portable electronics, Vishay Intertechnology has released two new low-capacitance electrostatic discharge (ESD) protection diode arrays that meet a high industry standard for ESD protection.
The new Vishay Semiconductors VESD05A8-HN2, housed in a 2.0 x 2.0-mm LLP70-9A package, features nine contact pads and a monolithic die with eight protection diodes. Previously, this quantity of diodes was only available in the larger 5.0 x 5.0-mm SO-8 package. As a result, the new array provides bidirectional asymmetrical (BiAs) protection for eight data lines, or bidirectional symmetrical (BiSy) protection for seven data lines.
The new VESD05A6-HA3 is packaged in a smaller 1.6 x 1.6-mm LLP75-7A package, and features seven contact pads and a monolithic die with six protection diodes. The array offers bidirectional asymmetrical (BiAs) protection for six data lines or bidirectional symmetrical (BiSy) protection for five data lines.
The new leadless SMD arrays meet a high industry standard for ESD protection, supplying transient protection of 30 kV (air) and 30 kV (contact) as per IEC 61000-4-2, as well as 5-A protection against lightning as per IEC 61000-4-5. Their low capacitance minimizes distortion to the operating signal on protected lines, said the company.
In protecting very sensitive mobile electronics such as mobile phone handsets, smart phones, laptop computers, PDAs, digital cameras, and MP3 players against electronic discharge pulses caused by user contact with displays and keypads, the ESD diode arrays also protect power supply and data transfer connections against discharge spikes. The devices' superior protection capability in a single compact package not only saves space, enabling design of smaller and/or more robust electronics, but also reduces manufacturers' component costs, said the company.
The VESD05A6-HA3 array is priced at $18.00 per 100 pieces, and $20.00 per 100 pieces for the VESD05A8-HN2, in quantities of 100,000 for U.S. delivery. Samples are available now. Production quantities with lead times of 8 to 12 weeks for larger orders will be available in late second quarter 2005 for the VESD05A6-HA3 and late third quarter for the VESD05A8-HN2.
