ESD5V3U4RRS
Ultra-Low Capacitance ESD Diode Array
• Rail-to-rail diodes with internal TVS diode
• ESD / transient protection of four I/O lines
and one Vcc line exceeding:
IEC61000-4-2 (ESD): ± 15 kV (contact)
IEC61000-4-4 (EFT): 2.5 kV / 50 A (5/50 ns)
IEC61000-4-5 (surge): 3 A (8/20 µs)
• Reverse working voltage data lines: 5.3 V max.
• Reverse working voltage Vcc: 6 V max.
• Very low capacitance: 0.4 pF typ.
• Very low reverse current < 10 nA typ.
• Very low clamping voltage:
12 V typ. at positive transients
4 V typ. at negative transients
• Pb-free (RoHS compliant) package
Applications
• USB 2.0 ports and future USB 3.0 ports
• Ethernet port: 10/100/1000 Mb/s
• IEEE 1394 FireWire ports
• Mobile communications e.g. high-speed
SIM card protection
• Consumer products (STB, DVD, DSC, DVC...)
• Notebooks and desktop computers, peripherals
