描述 Description

CS2203-25 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 4.5pF only, CS2203-25 is designed to protect parasitic-sensitive systems against over-voltage and over-current transient events. It complies with IEC 61000-4-2 (ESD), Level 4 (15kV air, 8kV contact discharge), IEC 61000-4-4 (electrical fast transient - EFT) (40A, 5/50 ns), IEC 61000-4-5 (Surge) (10A, 8/20s), very fast charged device model (CDM) ESD and cable discharge event (CDE), etc.
CS2203-25 is in a DFN-8L package. Each CS2203-25 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 CS2203-25 ideal for high-speed data port and high-frequency line (e.g., Gigabit Ethernet Ports) applications. The low clamping voltage of the CS2203-25 guarantees a minimum stress on the protected IC.
