SY205231DWD is an ultra-low capacitance transient voltage suppressor (TVS) designed to provide electrostatic discharge (ESD) protection for high-speed data interfaces. With a typical capacitance of 0.28pF, SY205231DWD is designed to protect against over-voltage and over-current transient events. It complies with IEC61000-4-2 (ESD) (±20kV air, ±20kV contact discharge), IEC61000-4-5 (surge) (10A, 8/20μs).

The combined features of ultra-low capacitance, ultra-small size, and high ESD robustness make SY205231DWD ideal for high-speed data ports and high-frequency lines (e.g., USB3.x& DVI) applications. The low clamping voltage of the SY205231DWD guarantees minimum stress on the protected IC.

Each SY205231DWD device can protect one high-speed data line. The SY205231DWD is available in a small DFN1.0×0.6-2 package.
