CH412Z

The CH412 is a quad ESD protection diode array capable of withstanding ESD pulses of up to ±15 KV human body model (HBM), ±8 KV contact discharge, and ±15 KV air - gap discharge as specified in IEC61000 - 4 - 2. It is used for ESD protection of high - speed signals, differential signals, and general signals in the external interfaces of electronic products. The CH412K provides 4 - channel low - capacitance diode protection and TVS transient voltage suppressor clamping. It is suitable for high - speed and medium - to - low - speed signals and can be used for USB SuperSpeed, High - Speed, Full - Speed, and Low - Speed signal protection. The CH412Z provides 4 - channel TVS transient voltage suppressor clamping. It is suitable for medium - to - low - speed signals and can be used for USB Full - Speed and Low - Speed signal protection.
