The SP0502B is a low capacitance TVS diode array designed to protect high-speed data interfaces from over-voltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). It has a typical capacitance of only 0.3pF (pin 1 to 2) making it suitable for use on circuits operating in excess of 3GHz without signal attenuation.

The SP0502BXTG is in a small SOT-523 package and each device can be configured to protect 1 bidirectional line or two unidirectional lines. The combination of small size, ultra-low capacitance, and high level of ESD protection makes it an ideal solution for applications such as HDMI, USB, MDDI, antennas, and DisplayPort circuits.


  • ESD protection of ±15kV contact discharge, ±20kV air discharge, (IEC61000-4-2)
  • EFT, IEC61000-4-4, 40A (5/50ns)
  • Lightning protection, IEC61000-4-5, 2A(tp=8/20μs)
  • Stand-off voltage of 5V
  • Low capacitance of 1pF @VR=0V (MAX)
  • Low leakage current of 0.5μA at 5V (MAX)
  • Small form factor (SOT523) and low profile(<1mm)
  • No insertion loss to >3.0GHz


  • High-Definition Multimedia Interface (HDMI)
  • Mobile Display Digital Interface (MDDI)
  • RF/Antenna Circuits
  • USB 2.0
  • DisplayPort Protection
