Infineon ESD112-B1-02ELE6327: Bidirectional ESD Protection Diode for High-Speed Data Lines

In the realm of modern electronics, safeguarding sensitive integrated circuits (ICs) from electrostatic discharge (ESD) and electrical overstress (EOS) is paramount. The Infineon ESD112-B1-02ELE6327 stands out as a premier solution, engineered specifically to provide robust protection for high-speed data interfaces. This bidirectional ESD protection diode is a critical component for ensuring the reliability and longevity of consumer electronics, communication systems, and computing hardware.

The core function of the ESD112-B1-02ELE6327 is to clamp hazardous voltage transients before they can damage the sensitive circuitry they are connected to. It is designed to meet the stringent requirements of high-speed data lines, such as those found in USB 3.0/3.1, HDMI, DisplayPort, and high-frequency serial interfaces. Its exceptionally low capacitance, typically just 0.35pF, is a key feature that prevents signal integrity degradation. This ensures that the protection device itself does not introduce data errors, attenuation, or distortion, which is absolutely critical for maintaining the integrity of multi-gigabit data transmissions.

Housed in an ultra-miniaturized SOT-523 (SC-79) package, this diode offers a compact footprint that is ideal for space-constrained PCB designs. Despite its small size, it delivers outstanding ESD robustness, capable of withstanding ESD strikes up to ±20 kV (air gap) and ±16 kV (contact discharge) as per the IEC 61000-4-2 international standard. Its bidirectional nature simplifies circuit design by providing protection for both positive and negative voltage swings with a single component, enhancing board layout efficiency.

The combination of low clamping voltage and fast response time ensures that the transient energy is diverted away from the protected IC almost instantaneously. This makes the ESD112-B1-02ELE6327 an indispensable guardian for ports and connectors that are frequently exposed to ESD events during hot-plugging or everyday use.

ICGOOODFIND: The Infineon ESD112-B1-02ELE6327 is an optimal choice for designers seeking invisible protection for high-speed data lines. Its ultra-low capacitance preserves signal integrity, while its superior clamping performance and miniature form factor provide a reliable and efficient defense against ESD, making it an essential component for next-generation electronic devices.
