Overview

The USBLC6-2P6 is a monolithic, very low capacitance ESD protection device designed specifically for high-speed USB 2.0 interfaces. It provides dual-line data protection and VBUS protection in a compact SOT-666 package, ensuring signal integrity while meeting IEC 61000-4-2 level 4 standards. The rail-to-rail steering diode architecture minimizes parasitic capacitance to maintain the high-speed data rates required for modern peripherals.

Why Choose This Part

The device features a very low capacitance that prevents signal distortion on high-speed lines and ensures consistent balance between D+ and D- signals. Its integrated design protects both the data lines and the VBUS power line, reducing component count and saving PCB real estate in space-constrained designs.

Applications

USB 2.0 High-Speed Ports
Protects D+ and D- lines in computers and peripherals while maintaining signal balance and impedance matching.
Ethernet 10/100 Interfaces
Provides transient voltage suppression for network ports without degrading the fast data signals.
SIM Card Protection
Safeguards the sensitive contacts of SIM card readers in mobile and IoT devices from electrostatic discharge during card insertion.
Video Signal Lines
Protects high-frequency video output lines in portable electronics where space and signal clarity are critical.

Getting Started

When laying out the PCB, place the USBLC6-2P6 as close as possible to the USB connector to minimize the path of the ESD strike. Ensure the ground trace is short and wide to reduce inductance, and route the differential data pairs through the device pins to maintain trace symmetry.
