TVS Diode Array

TVS Diode Array

Littelfuse, Inc. has introduced the SR05 Series  - SPA® Diodes, designed to protect telecommunication and industrial equipment against electrostatic discharge (ESD) and lightning-induced surge events.  Each channel or I/O pin can safely absorb up to 25A and repeated ESD strikes without performance degradation. Modern chipsets are highly susceptible to damage because of their extremely thin oxide layers and shallow transistor junctions. SR05 Series devices' extremely low dynamic resistance and clamping voltage levels ensure their ability to protect today's small geometry chipsets from damaging transients. With very low capacitance from each I/O to ground, these devices provide robust protection maintaining signal integrity, preventing data loss during transmission.

Typical applications of SR05 Series include protecting high-speed interfaces such as T1/E1/T3/E3 lines, Ethernet 10BaseT lines, WAN/LAN equipment, ISDN S/T interfaces, video lines, microcontroller inputs, USB1.1 ports, etc.

Features:

  • Low capacitance of 6pF from I/O to GND
  • Robust surge protection: lightning, IEC61000-4-5, 25A (8/20µs); peak  pulse power, 450W (8/20µs)
  • Enhanced ESD capability: IEC61000-4-2, ±30kV contact, ±30kV air
  • Enhanced ESD protection far exceeds the highest level of the IEC61000-4-2 standard (±8kV), allowing manufacturers that incorporate SR05 Series devices into their products to ensure maximum reliability in the field.

The SR05 Series  is available in quantities of 3,000 in tape and reel packaging. Samples are available now for bulk orders; sample requests can be placed through authorized Littelfuse distributors worldwide.
