The Littelfuse SP3205 provides low capacitance, unidirectional and a high level of protection for electronic equipment that may experience destructive electrostatic discharges (ESD). The typical capacitance of 0.3pF helps ensure excellent signal integrity on the most challenging consumer electronics interfaces, such as

ESD, IEC 61000-4-2, ±30kV contact, ±30kV air
EFT, IEC 61000-4-4, 40A (5/50ns)
Lightning, 4A (8/20μs as defined in IEC 61000-4-5 2nd edition)
Low capacitance of 0.3pF (TYP @ VR=0V)
Low leakage current of 1nA (TYP) at 3.3V
Halogen free, lead free and
