Description
The SP4021 devices integrate low capacitance steering diodes with one or two zener diodes for unidirectional or bidirectional protection, respectively, to protect against ESD and lightning induced surge events.
Features
- ESD, IEC61000-4-2, ±30kV contact, ±30kV air.
- Low leakage current.
- Unidirectional and Bidirectional configuration.
- Small SOD323 package fits 0805 footprints
