1. General description
Ultra low capacitance rail-to-rail ElectroStatic Discharge (ESD) protection diode in a small
SOT143B Surface-Mounted Device (SMD) plastic package designed to protect two Hi-Speed data
lines or high-frequency signal lines from the damage caused by ESD and other transients.
PRTR5V0U2X incorporates two pairs of ultra low capacitance rail-to-rail diodes as well as an
additional ESD protection diode to ensure signal line protection even if no supply voltage is
available.
2. Features and benefits
• ESD protection of two Hi-Speed data lines or high-frequency signal lines
• Ultra low input/output to ground capacitance: C(I/O-GND) = 1 pF
• 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 ports
• Digital Video Interface (DVI) / High Definition Multimedia Interface (HDMI) interfaces
• Mobile and cordless phones
• Personal Digital Assistants (PDA)
• Digital cameras
• Wide Area Network (WAN) / Local Area Network (LAN) systems
• PCs, notebooks, printers and other PC peripherals
