Littelfuse, Inc. has announced the new SP33R6 series of four-channel, low capacitance (0.2pF) TVS diode arrays that provide extremely low breakdown/turn-on voltages, making them ideal protectors of high-speed data lines with low voltage (-0.3 to +0.3V). These robust diodes without performance degradation can safely absorb repetitive ESD strikes above the maximum level specified in IEC 61000-4-2 international standard (Level 4, ±8kV contact discharge). Moreover, these diodes are ideal for use in a wide range of data communications interfaces for consumer electronics, including USB 3.2 and 4.0, Thunderbolt 3.0 and 4.0, and PCI Express 6.0.



  • Compliant with numerous IEC standards for ESD suppression and lightning surge protection, including IEC 61000-4-2, ±12kV contact, ±15kV air

  • Surge Tolerance, 3A (8/20μs) IEC 61000-4-5, 2nd Edition

  • Provides four channels with 0.2pF low capacitance per I/O to protect ultra-high-speed interfaces

  • An environmentally friendly component that is halogen-free, lead-free, and RoHS compliant



  • USB 3.2, USB 4.0

  • Thunderbolt 3.0

  • PCIE



The SPxxR6 series is now available and is provided in tape and reel format in quantities of 1,000.
