Typical Application


SYS11U12AMC is an ultra-low capacitance ESD and Surge Protector designed to provide electrostatic discharge (ESD) protection for high-speed data interfaces. SYS11U12AMC is designed to protect parasitic-sensitive systems against over-voltage and over-current transient events. It complies with IEC 61000-4-2(ESD), (±30kV air, ±30kV contact discharge), IEC 61000-4-5(Surge) (550W, 8/20μs), etc.


SYS11U12AMC is in an SOD-323 package. The combined features of ultra-low capacitance and high ESD robustness make SYS11U12AMC ideal for applications where arrays are not practical. The low clamping voltage of the SYS11U12AMC guarantees a minimum stress on the protected IC.
