    USB-OTG bus port protection array with low capacitance leakage current

Vishay Intertechnology launched a compact new ESD-protection array featuring a low capacitance and leakage current to protect USB-OTG ports against transient voltage signals. The new device, VBUS053AZ-HAF provides three lines of USB ESD protection at a 5.5-V working range, and one line of VBUS protection at a 12-V working range.

The device is ideally suitable for active ESD protection in high-speed data applications, such as USB 2.0 and HDMI in HDTVs and mobile electronics, including portable gaming systems, MP3 players, and cell phones.

The new device features:

1. A low load capacitance of 0.7 pF for the three data lines D+, D-, and ID
2. A low maximum leakage current of 0.085 µA at the working voltage of 3.3 V, and 1 µA at 5.5 V.
3. A low maximum clamping voltage of less than 4.1 V at 3 A for the data lines, and less than 30 V at 8 A for the VBUS line.
4. Provides transient protection as per IEC 61000 4 2 (ESD) at 15 kV (air and contact discharge), and IEC 61000 4 5 (lightning) from 3 A.

Package: LLP75-7L package
Size: 1.6-mm x 1.6-mm x 0.6 mm

Availability: Samples of the new USB-OTG bus port protection array are available now. Production quantities will be available in Q4 2008, with lead times of ten weeks for large orders.

Safety features: The lead-free device features a halogen-free molding compound, and is compliant with RoHS 2002/95/EC and WEEE 2002/96/EC.
