The SP3222 includes low capacitance rail to rail diodes with an additional Zener diode to provide 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 the IEC61000-4-2 international standard (±30kV contact discharge) without performance degradation. The low loading capacitance makes it ideal for protecting high speed data lines such as DVI, USB2.0, USB3.0 and eSATA.
- ESD protection of ±30kV contact discharge, ±30kV air discharge, (IEC61000-4-2)
- EFT, IEC61000-4-4, 40A (5/50ns)
- Lightning protection, IEC61000-4-5 2nd edition, 3A (tp=8/20μs)
- Low capacitance of 0.9pF @ VR=0V (MAX)
- Space efficient 0402 (SOD883) footprint
- Extremely low dynamic resistance (0.17Ω TYP)
- Moisture Sensitivity Level (MSL-1)
- AEC-Q101 qualified
- Halogen free, Lead free and RoHS compliant
