Infineon ESD231-B1-W0201: TVS Diode Array for High-Speed Interface ESD Protection

In the realm of modern electronics, protecting sensitive high-speed data interfaces from electrostatic discharge (ESD) and electrical overstress (EOS) is paramount. The Infineon ESD231-B1-W0201 stands out as a state-of-the-art TVS diode array specifically engineered to provide robust protection for high-speed lines such as USB 2.0, HDMI, and other high-frequency data ports. This device combines ultra-low capacitance with superior clamping performance, making it an ideal solution for space-constrained and performance-driven applications.

The core strength of the ESD231-B1-W0201 lies in its extremely low dynamic resistance (RDYN) and low clamping voltage, which ensures that transient voltage spikes are suppressed effectively before they can damage the protected IC. With a remarkably low typical capacitance of just 0.35 pF per channel, it minimizes signal integrity degradation, making it perfectly suited for high-speed data lines operating at multi-Gbps rates. The array offers ESD protection up to ±20 kV (contact discharge per IEC 61000-4-2), providing a high level of immunity against common ESD events encountered during manufacturing or end-user handling.

Housed in a compact W0201 (0402) package, this TVS array is designed for high-density PCB layouts, allowing designers to implement robust protection without compromising board space. Its bi-directional channel configuration and integration of multiple diodes in a single package simplify circuit design and enhance reliability. Furthermore, the device supports automated assembly processes, facilitating efficient manufacturing while reducing overall system cost.

ICGOODFIND: The Infineon ESD231-B1-W0201 is an exceptional choice for designers seeking to enhance the reliability of high-speed interfaces. Its combination of ultra-low capacitance, high ESD robustness, and miniaturized form factor addresses the critical needs of modern portable and high-performance electronic devices.
