Infineon ESD5V3U2U-03LRH: Ultra-Low Capacitance ESD Protection Diode for High-Speed Data Lines

In the realm of modern electronics, protecting sensitive integrated circuits from electrostatic discharge (ESD) is a critical design challenge, especially for high-speed data interfaces. The Infineon ESD5V3U2U-03LRH stands out as a premier solution, engineered specifically to safeguard high-frequency data lines while maintaining signal integrity.

This device is a bi-directional ESD protection diode housed in an ultra-compact LL1006-3L (0402) package, making it ideal for space-constrained PCB designs. Its primary role is to clamp dangerously high voltage transients caused by ESD strikes, diverting excess current away from vulnerable chips and thereby preventing latch-up or permanent damage.

A key feature of the ESD5V3U2U-03LRH is its exceptionally low typical capacitance of just 0.3 pF. This ultra-low capacitance is paramount for high-speed applications, as it minimizes signal distortion, preserves rise/fall times, and ensures minimal impact on data eye diagrams. This makes it perfectly suited for protecting interfaces such as USB 3.0/3.1, HDMI, DisplayPort, and high-frequency RF antenna lines.

The diode offers robust protection, meeting the IEC 61000-4-2 (Level 4) standard with outstanding performance. It can handle ESD strikes up to ±20 kV (air gap) and ±16 kV (contact discharge). Furthermore, it features a low clamping voltage, ensuring that the voltage seen by the protected IC is kept to an absolute minimum during a surge event.

Designed for automated assembly processes, its small form factor and compatibility with reflow soldering streamline manufacturing. With its combination of miniaturized size, superior protection level, and negligible signal degradation, the ESD5V3U2U-03LRH is an essential component for ensuring the reliability and longevity of cutting-edge consumer and industrial electronics.
