Typical Application


SYT03S05SHC is an ultra-low capacitance Transient Voltage Suppressor (TVS) designed to provide electrostatic discharge (ESD) protection for high-speed data interfaces. With typical capacitance of 0.3pF(I/O-I/O) only, SYT03S05SHC is designed to protect parasitic-sensitive systems against over-voltage and over-current transient events. It complies with IEC 61000-4-2(ESD), (±20kV air, ±20kV contact discharge), IEC 61000-4-5 (Surge) (4A, 8/20μs), etc.

SYT03S05SHC uses small DFN1.2*1.0-6L package. Each SYT03S05SHC device can protect two high-speed data lines. The combined features of low capacitance, small size and high ESD robustness make SYT03S05SHC ideal for high-speed data ports and high-frequency lines (e.g., USB2.0 & DVI) applications. The low clamping voltage of the SYT03S05SHC guarantees a minimum stress on the protected IC.
