SP1255P Series - 0.5pF, 12kV Diode Array for μUSB

Roll Over to Zoom

SP1255P Series Low Capacitance ESD Protection TVS Diode Arrays (SPA® Diodes) provide superior ESD protection for current-intensive applications. They integrate three channels of ultra-low capacitance steering diodes with a low voltage TVS diode to provide maximum ESD protection of the USB data and ID pins per the IEC 61000-4-2 standard. They provide clamping voltages up to 23 percent lower than similar silicon solutions. A high surge current protection device protects against lightning level fast transients of up to 100A on the USB Vbus line.


  • 100A peak current ESD protection for Vbus line
  • Data line ultra low dynamic resistance of 0.3Ω
  • 4A peak current protection for USB data pin
  • Small form factor µDFN-6 package (1.8x2.0x0.55 mm) allows straight-through routing
  • AEC-Q101 qualified


  • Smartphones
  • Tablets
  • USB 2.0 port
  • Micro USB
  • PoweredUSB
