USBLC6-4SC6Y - ST

The USBLC6-4SC6Y from STMicroelectronics is an automotive-grade quad-line ESD protection device housed in a compact SOT-23-6 package, designed specifically for high-speed USB 2.0 and Ethernet interfaces. It features ultra-low line capacitance of just 2.5pF typical, ensuring signal integrity on differential data lines up to 480Mbps without introducing significant insertion loss. Each I/O pin protects one interface line, and the monolithic structure integrates a voltage regulator to deliver well-controlled clamping action for both ESD strikes per IEC 61000-4-2 Level 4 (±15kV air, ±8kV contact) and fast transient bursts. The device also provides protection for VBUS power rails up to 5.5V, often used in conjunction with USBLC6-2 for a complete USB port protection solution. Typical applications include USB 2.0 ports, Ethernet PHYs, SIM card interfaces, and multimedia links in automotive infotainment, consumer electronics, and industrial control systems. AEC-Q101 qualified and RoHS compliant, it operates across -40°C to +150°C, making it a reliable choice for harsh-environment connectivity protection.
