USB0403 - USB0424C
350 WATT LOW CAPACITANCE TVS ARRAY
ISO 9001: 2015 CERTIFIED
DESCRIPTION
The USB04xx and USBxxC Series of devices are low capacitance TVS arrays available in a SOT-143 package. These
devices are designed to protect Ethernet data I/O ports against the damaging eects of ESD and EFT transient threats.
The USB04xx series are unidireconal devices used for common mode protecon from line to ground. The USB04xxC
series are bidireconal devices typically used for dierenal mode on balanced lines.
Voltages range from 3.3 to 24 volts for both conguraons. Each series provides ESD protecon to > 25 kilovolts with
a peak pulse power rang of 350 Was for an 8/20µs waveshape. The USB04xx and USBxxC series are designed to
meet and exceed the IEC 61000-4-2 and IEC 61000-4-4 requirements.
FEATURES

• Line 2 (TX) is connected to pins 2 and 3.
CIRCUIT BOARD RECOMMENDATIONS
Circuit board layout is crical for electromagnec compability protecon. The following guidelines are recommended:
• The protecon device should be placed near the input terminals or connectors, the device will divert the transient current
immediately before it can be coupled into the nearby traces.
• The path length between the TVS device and the protected line should be minimized.
• All conducve loops including power and ground loops should be minimized.
• The transient current return path to ground should be kept as short as possible to reduce parasic inductance.
• Ground planes should be used whenever possible. For mullayer PCBs, use ground vias.
