SP3051-04HTG

The SP3051-04HTG is a 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. It has advantages over similar devices include lower dynamic resistance for 35% lower clamping voltage and a much higher contact discharge ESD contact rating.

• Extremely low dynamic resistance (RDYN) of 0.3Ω
• Low capacitance from I/O to GND
• 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)
• Reduces clamping voltages up to 35% compared to competition
• Better able to protect modern ICs against industry-defined transients such as the IEC61000-4-5
• Capacitance up to 15% lower than similar market solutions
• Helps to preserve signal integrity by minimizing data loss in long installations of 1Gb Ethernet
• High power and surge handling capability offers more design margin to electrical threats
• -40 to 125°C Operating temperature range
