500 WATT ULTRA LOW CAPACITANCE TVS ARRAY
DESCRIPTION
The SLVU2.8-8G is an ultra low capacitance TVS array, designed to protect four line pairs from the effects of Electrostatic Discharge (ESD), Electrical Fast Transients (EFT) and switching transients. The SLVU2.8-8G exceeds Level 4 IEC
61000-4-2, with a peak pulse power rating of 500 Watts for an 8/20µs waveshape.
The ultra low capacitance and low leakage current of the device allows the designer to protect high speed data applications. Packaged in a SO-8 configuration, the SLVU2.8-8G is both RoHS and REACH compliant.

The SLVU2.8-8G provides four line pairs in a differential mode configuration. Circuit connectivity is as follows:
• Line Pair 1 connected to Pins 1 & 2
• Line Pair 2 connected to Pins 3 & 4
• Line Pair 3 connected to Pins 5 & 6
• Line Pair 4 connected to Pins 7 & 8
CIRCUIT BOARD RECOMMENDATIONS
Circuit board layout is critical for electromagnetic compatibility protection. The following guidelines are recommended:
• The protection 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 conductive 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 parasitic inductance.
• Ground planes should be used whenever possible. For multilayer PCBs, use ground vias.
