1. General description
Ultra low capacitance quadruple rail-to-rail ElectroStatic Discharge (ESD) protection device in an
SOT457 (SC-74) small Surface-Mounted Device (SMD) plastic package.
The device is designed to protect four high-speed data lines or high-frequency signal lines from the
damage caused by ESD and other transients.
PRTR5V0U4D integrates four ultra low capacitance rail-to-rail ESD protection channels and
one additional ESD protection diode to ensure signal line protection even if no supply voltage is
available.
2. Features and benefits

• ESD protection up to 8 kV
• IEC 61000-4-2, level 4 (ESD)
• Very low clamping voltage due to an integrated additional ESD protection diode
• Very low reverse current
• Small SMD plastic package
3. Applications
• USB 2.0 interfaces
• Digital Video Interface (DVI)
• High-Definition Multimedia Interface (HDMI)
• Mobile phones
• Digital cameras
• WAN/LAN systems
• PC, notebooks, printers and other PC peripherals
