A RailClamp is a low capacitance TVS array designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and Lightning.

The unique design incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. During transient conditions, the steering diodes direct the transient current away from the protected IC. The internal TVS diode clamps the transient voltage to a safe level. The low capacitance array configuration allows the user to protect up to two high-speed data lines.

Features:

• Transient protection for high-speed data lines to
  • IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
  • IEC 61000-4-4 (EFT) 40A (5/50ns)
  • IEC 61000-4-5 (Lightning) 24A (1.2/50μs)
• Array of surge rated diodes with internal TVS Diode
• Protects up to two I/O lines
• Low capacitance: <5pF (Line-to-Line)
• High surge capability: 40A (tp=8/20μs)
• Low operating voltage: 2.5V
