The SP1064 is an avalanche breakdown diode fabricated in a proprietary silicon avalanche technology protect each I/O pin to provide a high level of protection for electronic equipment that may experience destructive electrostatic discharges (ESD). These robust diodes can safely absorb repetitive ESD strikes above the maximum level specified in IEC 61000-4-2 international standard (Level 4, ±8kV contact discharge) without performance degradation. Their very low loading capacitance also makes them ideal for protecting high speed signal pins.
ESD, IEC 61000-4-2, ±15kV contact, ±20kV air
EFT, IEC 61000-4-4, 40A (5/50ns)
Lightning, 2A (8/20μs as defined in IEC 61000-4-5, 2nd Edition)
Low capacitance of 8.5pF (TYP) per I/O
Low leakage current of 0.05μA (TYP) at 60V
Small form factor μDFN (JEDEC MO-229) package saves board space
