CS2201-33 - RJ45 Ethernet L-L Surge Protection



  • Pretty low leakage current (<1μA) at working voltage of 3.3V
  • 3.5pF ultra low parasitic capacitance for each line to GND
  • Good capacitance uniformity in the range of 0V to 3.3V
  • Lower trigger voltage (<4V) to  response earlier under EOS events
  • Ultra lower clamping voltage to protect ICs well
  • Tiny packageDFN2626-10L
  • Including GND pin for better ESD protection


CS2201-33 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 3.8pF only, CS2201-33 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) (25A, 8/20μs), very fast charged device model (CDM) ESD and cable discharge event (CDE), etc.

CS2201-33 is in a DFN2.6´2.6-10L package. Each CS2201-33 device can protect two high-speed line pairs. The combined features of low capacitance and high ESD robustness make CS2201-33 ideal for high-speed data port and high-frequency line (e.g., Gigabit Ethernet Ports) applications. The low clamping voltage of the CS2201-33 guarantees a minimum stress on the protected IC.
