Ultra Low Cap, 2 Line, Bidirectional ESD Protection

Add to Watch List

RailClamp® TVS arrays are ultra low capacitance ESD protection devices designed to protect high speed data interfaces. They are designed to replace 0201 size multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and other portable electronics. This device offers desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation.


  • High ESD withstand Voltage: +/-17kV (Contact and Air) per IEC 61000-4-2
  • Very small PCB area: 0.6mm2
  • Protects up to two high-speed data lines
  • Low reverse current: <5nA typical (VR=5V)
  • Working voltage: +/- 5V
  • Low capacitance: <0.4pF (VR=0V)
  • Low dynamic resistance: 0.90 Ohms (Typ)
  • Solid-state silicon-avalanche technology
