Littelfuse's new ultra-miniature TVS diodes for high data-rate and general purpose applications now available from Anglia

Littelfuse, Inc., the global leader in circuit protection has introduced an industry first: a new series of three unidirectional TVS diodes in space-saving 01005 flip chip packages (0.230mm x 0.430mm). Unidirectional protection is typically preferable to bidirectional protection, particularly on logic and data lines, which typically do not transit zero volts during standard operation.

The new SP3145 Series TVS Diodes (SPA® Diodes), based on fast-acting, semiconductor-based technology, can withstand multiple electrostatic discharge (ESD) events without wear-out or degradation. Its low nominal capacitance (0.35pF) makes this series ideal for interfaces running at high data rates approaching 5GHz clock speeds.

The general purpose SP1043 (8pF) and SP1044 (30pF) Series TVS Diodes employ proprietary silicon avalanche technology to protect the I/O ports of electronic equipment subject to destructive ESD. These robust diodes can safely absorb repetitive ESD strikes at ±12kV (for SP1043) or ±30kV (for SP1044) without performance degradation.

Typical applications for these TVS diodes include communications, imaging devices, wearable technology, tablet computers, data logging and other portable equipment due to the extremely compact size of the devices.

The SP3145, SP1043, and SP1044 Series TVS Diodes offer these key benefits:

  • Low capacitance unidirectional ESD protection in the industry's smallest footprint, to ensure data integrity while saving PCB space.
  • Provides ESD immunity beyond the maximum rating in the IEC61000-4- 2 standard, to enable circuit designers more design margin and higher end-product reliability in the field.
  • Low dynamic resistance (3.5Ω max for SP3145, 0.45Ω max for SP1043/SP1044) supports the low clamping voltage needed to protect modern electronics filled with small geometry ICs.
  • Low standoff voltage (6V max for SP1043/SP1044, 3.3V max for SP3045) enables protection of up to 95 percent of all interfaces.
