STMicroelectronics USBLC6-2SC6H: High-Speed USB Interface Protection

The USBLC6-2SC6H from STMicroelectronics is a robust transient voltage suppressor designed for the protection of high-speed interfaces, such as USB 2.0, from electrostatic discharges (ESD), electrical fast transients (EFT), and other harmful transient voltage conditions. This product is particularly well-suited for applications where the USB interface is exposed to external environments and is at risk of damage from electrostatic discharge and other voltage surges.

Key Features

• ESD Protection: The USBLC6-2SC6H offers an exceptional level of protection against ESD, exceeding the IEC 61000-4-2 level 4 standard with up to 15kV (air discharge) and 8kV (contact discharge) protection.
• Low Capacitance: With very low line capacitance, the device ensures signal integrity for high-speed data lines without compromising the data rate or signal quality.
• Low Leakage Current: It features a very low leakage current, thereby reducing power consumption and increasing the reliability of the system.
• High Surge Current Capability: The USBLC6-2SC6H is capable of withstanding high surge currents, ensuring robust protection for sensitive components downstream.
• Stand-Off Voltage: It has a stand-off voltage of 5.25V, which is suitable for USB power lines.

Applications

• USB 2.0 Power and Data Line Protection
• Smartphones, Tablets, and Portable Devices
• Peripheral Ports Protection
• Set-Top Boxes, Digital TVs, and DVD Players
• Other High-Speed Data Line Applications
