 This series is not recommended for new designs. Suggests to use SP3025-04HTG for the new designs in near future.

The SP3051-04HTG Transient Voltage Suppression (TVS) Diode Array (SPA® Diode) integrates low capacitance rail-to-rail diodes with an additional zener diode to protect I/O pins against ESD and lightning-induced surge events. This robust device can safely absorb 20A of current per IEC61000-4-5 (tP=8/20μs) without performance degradation and a minimum ±30kV ESD per IEC61000-4-2.Advantages over similar devices include lower dynamic resistance for 35% lower clamping voltage and a much higher contact discharge ESD contact rating.

Features:

  • Extremely low dynamic resistance (RDYN) of 0.3Ω
  • Low capacitance from I/O to GND (3.8pF @ 0V DC bias, 1.7pF @ VCC=5V, VI/O=2.5V)
  • Robust surge protection (Lightning, IEC61000-4-5, 20A (8/20µs); Peak pulse power, 400W (8/20µs))
  • Enhanced ESD capability (IEC61000-4-2, ±30kV contact, ±30kV air)

Benefits:
  • Reduces clamping voltages up to 35 percent compared to competition; better able to protect modern ICs against industry-defined transients such as the IEC61000-4-5
  • Capacitance up to 15 percent lower than similar market solutions; helps to preserve signal integrity by minimizing data loss in long (e.g., 100m) installations of 1Gb Ethernet
  • High power and surge handling capability offers more design margin to electrical threats defined by industry standards as well as Cable Discharge Events (CDE)
  • Enhanced ESD protection far exceeds the highest level of the IEC61000-4-2 standard (±8kV), ensuring maximum reliability of end products in the field

Applications:

Protection of high-speed ports:

  • 10/100/1000 Ethernet (PHY side)
  • T1/E1/T3/E3 (PHY side)
  • USB 2.0
  • FireWire

Protection of sensitive electronic equipment:
  • Switches
  • Gateways
  • Pico/femtocells
  • LCD/PDP TVs
  • Set-top boxes
  • Notebooks/ultrabooks
  • Diagnostic/medical equipment 
  • Monitors/flat panel displays
