Vishay Intertechnology Inc. has released a compact double-diode ESD-protection array designed to protect dual high-speed USB ports or up to two other high-frequency signal lines against transient voltage signals.

The VBUS052BD-HTF is packaged in the leadless LLP75, with a 1.6mm x 1.6mm footprint and an ultralow profile of 0.6mm. According to Vishay, the package, which uses an environmentally friendly 'green' molding compound, minimizes the board space required for active ESD protection in a wide range of portable electronics. Typical applications will include portable and handheld computing, communications, industrial, and medical systems.

The device features a low capacitance of 1.5pF typical per diode and a low maximum leakage current of The bus port-protection array provides transient protection for one data line as per IEC 61000 4 2 (ESD) at 15kV (contact and air discharge) and offers a high surge current >3A in accordance with IEC 61000 4 5. It is also compliant with RoHS 2002/95/EC and WEEE 2002/96/EC.

Samples and production quantities are available now.
