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.
