Vishay’s New Double-Diode Bus Port-Protection Array Provides Capacitance of 1.5 pF Typical per Diode and Maximum Leakage Current of <0.1 μA in Ultra-Compact LLP75 Leadless Package
Device Features Low Profile of 0.6 mm for Board Space Savings in Portable Electronics
MALVERN, Pa. — May 23, 2008 — Vishay Intertechnology, Inc. (NYSE: VSH) today released a compact new 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 1.6-mm by 1.6-mm footprint and an ultra-low profile of 0.6 mm. This tiny 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 new device features a low capacitance of 1.5 pF typical per diode and a low maximum leakage current of <0.1 μA at the working voltage of 5 V. The array offers a breakthrough voltage of typical 7.9 V (at 1 mA), and a maximum clamping voltage of 16 V at 3 A.
The bus port-protection array provides transient protection for one data line as per IEC 61000 4 2 (ESD) at ±15 kV (contact and air discharge) and offers a high surge current >3 A 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 of the new VBUS052BD-HTF double-diode ESD bus port-protection array in the compact LLP75 package are available now, with lead times of 10 weeks for large orders.
