Littelfuse SP3051-04HTG, 9-Element Uni-Directional TVS Diode Array, 400W, 6-Pin SOT-23

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 without performance degradation and a minimum ±30kV ESD. 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 (3.8pF @ 0V DC bias, 1.7pF @ VCC=5V, VI/O=2.5V)
Robust surge protection, Peak pulse power, 400W (8/20μs))
Enhanced ESD capability
Benefits:
Reduces clamping voltages up to 35 percent compared to competition, better able to protect modern ICs against industry-defined transients
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 ensuring maximum reliability of end products in the field
