Typical Application


SYS42L02FAC is an ultra low-capacitance Transient Voltage Suppressor (TVS) array designed to provide electrostatic discharge (ESD) protection for high-speed data interfaces. With typical capacitance of 1.2pF only, SYS42L02FAC 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), IIEC 61000-4-5 (Surge) (50A, 8/20μs), etc. 
SYS42L02FAC is in an SOP-8 package. Each SYS42L02FAC device can protect two high-speed line pairs. The “flow-thru” design minimizes trace inductance and reduces voltage overshoot associated with ESD events. The combined features of low capacitance and high ESD robustness make SYS42L02FAC ideal for high-speed data port and high-frequency line (e.g., Gigabit Ethernet Ports) applications. The low clamping voltage of the SYS42L02FAC guarantees a minimum stress on the protected IC.
