The SLVU2.8 is a low voltage, low leakage current and ultra low capacitance TVS device designed for EOS and ESD
protecon of low voltage circuits commonly found in network and compung applicaons. This device can be placed
at the connector input or at the sensive IC component and also be used across a single ended data line for the pro-
tecon of a single line.
The SLVU2.8 device meets the IEC requirements of 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (Surge). This de-
vice has a peak pulse power rang of 600 Was (8/20µs waveform) and is available in a SOT-23 package conguraon.

Circuit connecvity is as follows:
• Line 1 connected to Pin 3.
• Pins 1 and 2 connected to ground.
Circuit board layout is crical for electromagnec compability protecon. The following guidelines are recommended:
• The protecon 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 conducve 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 parasic inductance.
• Ground planes should be used whenever possible. For mullayer PCBs, use ground vias.
Two SLUV2.8 devices used in parallel. Circuit connecvity is as follows:
• Line 1 connected to Pin 1 of Device 1 and Pin 2 connected to Device 2.
• Pin 2 of Device 1 and Pin 1 of Device 2 connected to ground.
• Pin 3 of both Devices not connected.
