SY205210DHC is a low-capacitance transient voltage suppressor (TVS) array designed to provide electrostatic discharge (ESD) protection for high-speed data interfaces. With typical capacitance of 3.0pF, the SY205210DHC is designed to protect against over-voltage and over-current transient events. It complies with IEC 61000-4-2 (ESD) (±30kV air, ±30kV contact discharge), IEC 61000-4-4 (electrical fast transient - EFT) (40A, 5/50μs), IEC 61000-4-5 (surge) (40A, 8/20μs).
The combined features of low capacitance and high ESD robustness makes SY205210DHC ideal for high-speed data port and high-frequency line (e.g., Gigabit Ethernet ports) applications. The low clamping voltage of the SY205210DHC guarantees a minimum stress on the protected IC. The “flow-through” design minimizes trace inductance and reduces voltage overshoot associated with ESD events.
Each SY205210DHC device can protect two high-speed line pairs. The SY205210DHC is available in a compact DFN3.0×2.0-10 package.
