APPLICATION INFORMATION
FIGURE 1 - BIDIRECTIONAL COMMON-MODE PROTECTION
The SLVU2.8-8 provides 4 lines of protection in a common mode configuration. Circuit connectivity is as follows:
• Line 1 connected to Pin 1
• Line 2 connected to Pin 8
• Line 3 connected to Pin 5
• Line 4 connected to Pin 4
• Pins 2, 3, 6, 7 are connected to ground
FIGURE 2 - BIDIRECTIONAL DIFFERENTIAL-MODE PROTECTION
The SLVU2.8-8 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
• 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.
