APPLICATION NOTE
The LCA Series are low capacitance, bidirectional TVS arrays that are designed to protect I/O or high speed data lines from the damaging effects of
ESD or EFT. This product series has a surge capability of 800 Watts P
PP
per line for an 8/20s waveshape and offers ESD protection > 40kV.
BIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 1)
Ideal for use in USB applications, the LCD Series provides up to eight (8) lines of protection in a common-mode configuration as depicted in Figure
1.
Circuit connectivity is as follows:
Pins 2, 3, 4, 5, 6, and 7 are connected to ground.
Pins 15 and 14 connected to Port #1 D- and D+.
Pins 13 and 12 connected to Port #2 D+ and D-.
Pins 11 and 10 connected to Port #3 D+ and D-.
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. By placing the TVS
close to the connectors, the device will divert the
transient current immediately before it can be
coupled into the nearby traces.
The path length between the TVS devices 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.
