Overview

The USBLC6-2SC6 is a monolithic application-specific device dedicated to ESD protection of high-speed interfaces such as USB 2.0. It provides two channels of rail-to-rail protection with a very low capacitance, ensuring signal integrity for data rates up to 480 Mb/s.

Why Choose This Part

This device features a very low capacitance and low leakage current of 150 nA, which minimizes signal distortion on high-speed differential pairs. Its SOT-23-6 package integrates protection for two data lines and the VBUS power line, simplifying PCB layout and reducing component count.

Applications

USB 2.0 High-Speed Ports
Protects D+ and D- data lines in laptops, peripherals, and mobile devices while maintaining 480 Mb/s signal integrity.
Ethernet Protection
Used for 10/100 Mb/s Ethernet port protection to prevent damage from electrostatic discharge during cable insertion.
SIM Card Interfaces
Safeguards SIM card data lines in cellular modules and portable electronics from ESD events.
Video Line Protection
Protects sensitive analog or digital video interfaces against transient voltage spikes.

Getting Started

When laying out the PCB, place the USBLC6-2SC6 as close as possible to the USB connector to minimize parasitic inductance. Ensure the ground trace is short and wide to provide a low-impedance path to the system ground plane during an ESD event.
