1. General description

Ultra low capacitance double rail-to-rail ElectroStatic Discharge (ESD) protection diode in a small

SOT143B Surface-Mounted Device (SMD) plastic package.

The device is designed to protect two high-speed data lines or high-frequency signal lines from the

damage caused by ESD and other transients.

The device integrates two ultra low capacitance rail-to-rail diodes and one additional ESD

protection diode to ensure signal line protection even if no supply voltage is available.

2. Features and benefits
