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.
