1.1 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.

PRTR5V0U2AX 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.
