Infineon ESD5V3U4U-HDMIE6327: High-Performance ESD Protection Diode for HDMI Interfaces

The increasing demand for high-speed data transmission in modern consumer electronics, particularly through HDMI interfaces, necessitates robust protection against electrostatic discharge (ESD) events. The Infineon ESD5V3U4U-HDMIE6327 is a state-of-the-art protection diode specifically engineered to safeguard sensitive HDMI circuitry from voltage transients, ensuring both signal integrity and device reliability.

This diode array offers exceptional ESD robustness, exceeding the stringent requirements of the IEC 61000-4-2 standard (Level 4). It can withstand ESD strikes of up to ±30kV (air and contact discharge), providing a critical defensive barrier for connected equipment such as televisions, gaming consoles, and set-top boxes. Its ultra-low clamping voltage is paramount, as it swiftly diverts transient currents away from the protected IC, preventing latch-up and permanent damage.

A key advantage of the ESD5V3U4U-HDMIE6327 is its minimal impact on signal integrity. Designed for high-speed data lines, it features an extremely low capacitance of just 0.5pF (typical) and a low insertion loss. This ensures that the protection component does not distort the high-frequency HDMI signals, supporting data rates required for 4K and 8K video resolutions without compromising performance.

Furthermore, the component is optimized for space-constrained designs. Housed in a compact and leadless DSON-10 package, it provides a multi-channel solution that protects four HDMI lines simultaneously. This integration simplifies board layout, reduces the bill of materials (BOM), and enhances overall system reliability with a single component.

ICGOOODFIND: The Infineon ESD5V3U4U-HDMIE6327 stands out as a superior solution for HDMI port protection, combining maximum ESD resilience with transparent signal performance in a highly integrated package, making it an essential component for next-generation audiovisual interfaces.
