CS0801M - Low Capacitance TVS Protection


  • Ultra low leakage current (<1μA) at working voltage of 5.0V
  • 12pF parasitic capacitance for relatively low data rate signal lines
  • Lower trigger voltage to  response earlier under ESD events
  • Ultra lower clamping voltage to protect ICs well
  • Above ±30kV ESD protection level for IEC61000-4-2
  • Bi-directional for differential signal line pairs and easy to surface mounted without worrying wrong direction
  • Tiny packageDFN1006-2L (0402)


CS0801M is a low-capacitance Transient Voltage Suppressor (TVS) designed to provide electrostatic discharge (ESD) protection for data, control or power lines. With typical capacitance of 12pF only, CS0801M 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), very fast charged device model (CDM) ESD and cable discharge event (CDE), etc.

CS0801M uses ultra-small uDFN-2L package. Each CS0801M device can protect one data line. It offers system designers flexibility to protect single data line where space is a premium concern.
