1.1 General description

Ultra low capacitance single rail-to-rail ElectroStatic Discharge (ESD) protection device in

a small SOT23 (TO-236AB) Surface-Mounted Device (SMD) plastic package designed to

protect one Hi-Speed data line or high-frequency signal line from the damage caused by

ESD and other transients.

PRTR5V0U1T incorporates one ultra low capacitance rail-to-rail protection channel as

well as an additional ESD protection diode to ensure signal line protection even if no

supply voltage is available.

1.2 Features
