1. Description
The USBLC6-2SC6Y is a monolithic device dedicated to ESD protection of high speed interfaces, such as USB 2.0, Ethernet links and video lines. The very low line capacitance secures a high level of signal integrity without compromising in protecting sensitive chips against the most stringent characterized ESD strikes.
2. Features
1. 2 data lines protected
2. Protects VBUS
3. Very low capacitance: 2.5 pF
4. Very low leakage current: 10 nA
5. SOT23-6L package
6. RoHS compliant
7. AEC-Q101 qualified
3. Applications
1. USB 2.0 ports up to 480 Mb/s (high speed)
2. Compatible with USB 1.1 low and full speed
3. High-speed datalines in smart junction boxes
4. Ethernet port: 10/100 Mb/s
5. Video line protection
4. Benefits
1. Very low capacitance between lines to GND for optimized data integrity and speed
2. Low PCB space consumption
3. Enhanced ESD protection. ISO10605 up to 25 kV guaranteed at device level
4. ESD protection of VBUS
5. High reliability offered by monolithic integration
6. Fast response time
7. Consistent D+ / D- signal balance:
– Very low capacitance matching tolerance I/O to GND = 0.015 pF
