Low-capacitance ESD protection diode arrays come in tiny packages

Two low-capacitance ESD protection diode arrays extend the Vishay Semiconductors' line of ultra-small LLP-packaged products optimized for data-line protection in compact portable electronics. The VESD05A8-HN2, packaged in the 2.0- by 2.0-mm LLP70-9A, features nine contact pads and a monolithic die with eight protection diodes. Such a quantity of diodes that was only available in the larger 5.0- by 5.0-mm SO-8 package. As a result, the array provides bidirectional asymmetrical (BiAs) protection for eight data lines, or bidirectional symmetrical (BiSy) protection for seven data lines.

The VESD05A6-HA3 is packaged in the 1.6- by 1.6-mm LLP75-7A and features seven contact pads and a monolithic die with six protection diodes. The array offers BiAs protection for six data lines or BiSy protection for five data lines.

The two leadless SMD arrays meet a high industry standard for ESD protection, supplying transient protection of 30 kV 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.

Sample quantities of both arrays are available now, with production quantities coming shortly. Prices for 100,000-piece quantities are $18.00 per 100 pieces for the VESD05A6-HA3 and $20.00 per 100 pieces for the VESD05A8-HN2. For more information, go to www.vishay.com.
