Infineon ESD101-B1-02EL: High-Performance ESD Protection Diode for Circuit Safety

In the realm of modern electronics, robust electrostatic discharge (ESD) protection is non-negotiable. The Infineon ESD101-B1-02EL stands out as a premier solution designed to safeguard sensitive circuits from transient voltage events, ensuring reliability and longevity in a wide array of applications.

This protection diode is engineered with exceptional clamping performance, capable of handling ESD strikes up to ±30 kV (contact discharge) per IEC 61000-4-2 standards. Its ultra-low clamping voltage ensures that during an ESD event, the protected IC experiences only a minimal voltage surge, significantly reducing the risk of damage. The device features a remarkably low dynamic resistance, which contributes to its superior energy dissipation characteristics.

Housed in a compact SOD-323 package, the ESD101-B1-02EL is ideal for space-constrained PCB designs, such as those in smartphones, wearables, IoT modules, and high-speed data interfaces (e.g., USB 3.0, HDMI). Its bidirectional functionality allows for easy integration into both positive and negative supply lines without regard for polarity, simplifying design and layout.

Furthermore, the diode exhibits negligible leakage current and minimal capacitance, typically around 2.5 pF, making it suitable for high-speed data lines where signal integrity is paramount. It ensures that protection does not come at the cost of performance.

ICGOOODFIND: The Infineon ESD101-B1-02EL is a top-tier ESD protection diode, offering high robustness, low capacitance, and excellent clamping in a miniaturized form factor, making it an essential component for enhancing circuit safety in modern electronic designs.
