Infineon ESD112-B1-02ELS: High-Performance ESD Protection Diode for Sensitive Electronics

In the rapidly advancing world of electronics, protecting sensitive circuits from electrostatic discharge (ESD) is paramount. The Infineon ESD112-B1-02ELS stands out as a premier solution, engineered to provide robust protection for high-speed data interfaces in a remarkably compact package. This ultra-low capacitance ESD protection diode is specifically designed to safeguard sensitive components in applications such as USB 3.0/3.1, HDMI, and high-frequency data lines, where signal integrity is non-negotiable.

The core of the ESD112-B1-02ELS's superiority lies in its exceptionally low dynamic resistance and ultra-low clamping voltage. These characteristics ensure that when an ESD event occurs, the transient energy is diverted away from the protected IC quickly and efficiently, minimizing the voltage stress that reaches the sensitive circuit. This is crucial for preventing latent damage and catastrophic failures in modern chips fabricated with finer, more vulnerable process technologies.

Housed in a minuscule DFN1006-2 (SOD882) package, this diode offers superior performance without occupying significant board space, making it an ideal choice for the increasingly compact form factors of today's consumer and industrial electronics. Furthermore, its ultra-low capacitance of just 0.35 pF (typical) is a critical feature. This ensures that there is negligible signal distortion, attenuation, or degradation of data integrity, even for signals exceeding 5 Gbps. Designers no longer need to choose between protection and performance.

The device is characterized for ESD immunity up to ±20 kV (air and contact discharge, IEC 61000-4-2), providing a high level of confidence in its ability to withstand real-world ESD events. Its bi-directional functionality simplifies PCB layout by offering protection for both positive and negative voltage surges on a single data line.

ICGOOODFIND: The Infineon ESD112-B1-02ELS is an exemplary surface-mount protection component that masterfully balances miniaturization, unmatched signal integrity, and superior ESD robustness. It is an indispensable component for designers aiming to enhance product reliability and meet stringent international ESD compliance standards without compromising on speed or size.
