SLVU2.8-8
APPLICATION NOTE
Electronic equipment is susceptible to damage caused by Electrostatic Discharge (ESD), Electrical Fast Transients (EFT), and tertiary lightning effects.
Knowing that equipment can be damaged, the SLVU2.8-8 was designed to provide the level of protection required to safe guard sensitive equipment.
This product can be used in different configurations to provide a level of protection to meet bidirectional requirements either in a common-mode or
differential-mode configuration.
BIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 1)
Figure 1. Bidirectional Common-Mode Protection
The SLVU2.8-8 provides up to four lines of protection in a common-mode configuration as
depicted in figure 1.
Circuit connectivity is as follows:
✔
✔
✔
✔
✔
Line 1 is connected to Pin 1
Line 2 is connected to Pin 8
Line 3 is connected to Pin 5
Line 4 is connected to Pin 4
Pins 2, 3, 6 and 7 are connected to ground
BIDIRECTIONAL DIFFERENTIAL-MODE CONFIGURATION (Figure 2)
The SLVU2.8-8 provides up to four line paris of protection in a differential-mode configura-
tion as depicted in figure 2.
Circuit connectivity is as follows:
✔
✔
✔
✔
Line Pair 1 is connected to Pins 1 & 2
Line Pair 2 is connected to Pins 3 & 4
Line Pair 3 is connected to Pins 7 & 8
Line Pair 4 is connected to Pins 5 & 6
Figure 2. Bidirectional Differential-Mode Protection
CIRCUIT BOARD LAYOUT RECOMMENDATIONS
Circuit board layout is critical for Electromagnetic
Compatibility (EMC) 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.
