The SLVU2.8-4 is an ultra low capacitance TVS array that provides two line pairs of protecon. This device protects
high-frequency applicaons such as voice, video and data related systems and is designed to minimize the eects
of high overshoot voltage experienced during and ESD event. This device has an in-line design, which reduces lead
inductance thus providing lower overshoot voltage.
The SLVU2.8-4 meets IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 requirements. Packaged in an SO-8 congura-
on, this device is rated for 600 Was Peak Pulse Power, for an 8/20µs waveform.

The SLVU2.8-4 provides 4 lines of protecon in a common mode conguraon. Circuit connecvity is as follows:
• Line 1 connected to Pin 1.
• Line 2 connected to Pin 7.
• Line 3 connected to Pin 3.
• Line 4 connected to Pin 5.
• Pins 2, 4, 7 and 7 are connected to ground.
• External diode to ground is a low capacitance diode of less than 10pF.
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.
