Infineon ESD5V3U4RRS: Ultra-Low Capacitance ESD Protection Diode for High-Speed Data Interfaces
The relentless advancement in high-speed data communication, from USB4 and Thunderbolt™ to HDMI 2.1, demands not only faster data rates but also robust protection against electrostatic discharge (ESD). The Infineon ESD5V3U4RRS stands out as a critical component engineered specifically to meet this dual challenge, offering superior ESD protection while maintaining signal integrity in the most demanding high-frequency applications.
At the heart of this device's performance is its ultra-low diode capacitance, rated at a mere 0.35 pF (typical). This exceptionally low value is paramount for high-speed data lines, as any additional capacitance can lead to signal distortion, attenuation, and increased bit-error rates (BER). By minimizing this capacitive loading, the ESD5V3U4RRS ensures that the integrity of high-speed signals remains uncompromised, supporting data rates well into the multi-gigabit range.
The diode provides robust protection against ESD events, achieving IEC 61000-4-2 (Level 4) compliance with outstanding ratings of ±20 kV (air discharge) and ±16 kV (contact discharge). This ensures that sensitive integrated circuits (ICs) downstream are shielded from potentially catastrophic voltage spikes that can occur during manufacturing, handling, or end-user operation.
Housed in an ultra-miniature RSS0010A3 (UDFN-10) package, the device integrates four independent protection lines in a single, space-saving footprint. This makes it an ideal solution for protecting differential pairs commonly found in interfaces like USB, DisplayPort, and Ethernet. Its low clamping voltage efficiently diverts transient energy away from the protected IC, further enhancing system reliability.
Designers will also appreciate its very low leakage current, which helps in reducing overall power consumption—a vital consideration for portable and battery-powered devices. The combination of minimal capacitance, high ESD robustness, and a compact form factor makes the ESD5V3U4RRS an indispensable component for modern electronics design.
ICGOOFind: The Infineon ESD5V3U4RRS is a premier solution for safeguarding high-speed data interfaces. Its industry-leading ultra-low capacitance of 0.35 pF ensures impeccable signal integrity, while its superior ESD protection ratings guard against the toughest transient threats. Its compact, multi-channel design offers engineers a reliable and efficient way to protect advanced systems without compromising performance.
