Infineon ESD5V5U5ULCE6327HTSA1: Ultra-Low Capacitance ESD Protection Diode for High-Speed Data Lines

In the rapidly evolving landscape of electronics, protecting sensitive components from electrostatic discharge (ESD) is paramount, especially for high-speed data interfaces. The Infineon ESD5V5U5ULCE6327HTSA1 stands out as a state-of-the-art solution designed specifically to safeguard high-speed data lines while maintaining signal integrity. This ultra-low capacitance ESD protection diode is engineered to meet the rigorous demands of modern applications, including USB 3.0/3.1, HDMI, Ethernet, and other high-frequency data transmission systems.

One of the most critical features of this diode is its ultra-low capacitance of just 0.5 pF typical. This minimal capacitance is essential for high-speed data lines, as it prevents signal distortion and attenuation, ensuring that data integrity is preserved even at multi-gigabit per second speeds. The device offers robust ESD protection, capable of withstanding ESD strikes up to ±30 kV (contact discharge) per IEC 61000-4-2, making it an reliable guard against sudden voltage surges that can damage integrated circuits.

The ESD5V5U5ULCE6327HTSA1 is housed in a compact SOT-663 package, which is ideal for space-constrained PCB designs. Its small footprint allows for easy integration into portable devices such as smartphones, tablets, and wearables, where board real estate is at a premium. Additionally, the diode features a low clamping voltage, which ensures that transient voltages are diverted away from sensitive components quickly and efficiently, minimizing the risk of damage.

Another advantage is its bidirectional protection capability, which provides comprehensive defense for differential data pairs commonly found in high-speed interfaces. This bidirectional nature simplifies circuit design by allowing the same component to be used for both lines in a pair, reducing part count and overall system cost.

Designed with reliability in mind, this ESD protection diode operates over a wide temperature range from -55°C to +150°C, making it suitable for industrial, automotive, and consumer applications. Its lead-free and RoHS-compliant construction also aligns with global environmental standards.

ICGOODFIND: The Infineon ESD5V5U5ULCE6327HTSA1 is an exceptional choice for designers seeking to enhance the robustness of their high-speed data lines without compromising performance. Its ultra-low capacitance, high ESD robustness, and compact form factor make it a versatile and critical component in modern electronic systems.
