The SRDA3.3 Series TVS diodes combines low-capacitance steering diodes with a Zener diode to protect against electrostatic discharge (ESD) and high surges. The devices provide 40% greater protection without performance degradation than comparable products and 50% lower loading capacitance — 10pF (maximum).
Features and benefits include surge protection  – lightning, IEC61000-4-5, 35 A (8/20 µsec), peak pulse power, 600 W (8/20 µsec); 5-Ω dynamic resistance; low capacitance of 8 pF (typical) /10 pF (maximum) from I/O to GND; enhanced ESD capabilities – ESD, IEC61000-4-2, ±30-kV contact, ±30-kV air, and very-low clamping voltages for sensitive chipsets.
