Bidirectional TVS Diode Array Sports Lower Standoff Voltages

Littelfuse’s 80A discrete bidirectional TVS diode arrays offer circuit designers lower standoff voltage options for protecting lower voltage power buses from electrostatic discharge (ESD) damage. Fabricated in a proprietary silicon avalanche technology, the diodes protect each I/O pin to provide a high level of protection for electronic equipment sensitive to destructive ESDs. They can safely absorb repetitive ESD strikes at ±30kV without performance degradation. Additionally, each diode can safely dissipate 80A of 8/20µs surge current with very low clamping voltages. Applications include automotive electronics, industrial products, consumer electronics, switches/buttons, test equipment/instrumentation, point-of-sale terminals, medical equipment, notebooks/desktops/servers, and computer peripherals. Benefits include:

  • 0.01Ω dynamic resistance ensures fast-acting ESD protection during an overvoltage event.
  • bidirectional design allows devices to work whether they are inserted forward or backward.
  • low breakdown voltages (3.3V) protect power rails up to 2.8V.
  • industry-standard leadless 1610DFN package suitable for use in industrial, automotive, and commercial environments.


The SP1103C Series in surface-mount 1610DFN packages is provided in tape & reel format in quantities of 3,000. Additional information is available on the SP1103C TVS Diode Arrays as well as a datasheet.
