CH412K

CH412 is a quad-channel ESD protection diode array capable of withstanding ESD pulses up to ±15KV Human Body Model, ±8KV contact discharge, and ±15KV air-gap discharge as specified by IEC 61000-4-2. It is designed for ESD protection of high-speed signals, differential signals, and general-purpose signals on external interfaces of electronic products. CH412K provides 4-channel low-capacitance diode protection with TVS clamping, suitable for high-speed and medium-to-low-speed signals. It can be used for USB SuperSpeed, High-Speed, Full-Speed, and Low-Speed signal protection. CH412Z provides 4-channel TVS clamping, suitable for medium-to-low-speed signals. It can be used for USB Full-Speed and Low-Speed signal protection.
