APPLICATION NOTE
The PSRDAxx-6 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 500 Watts P
PP
per line for an 8/20μs waveshape and offers ESD protection >
40kv.
DIFFERENTIAL MODE CONFIGURATION (Figure 1)
Ideal for use in USB applications, the PSRDAxx-6 Series provides up to six (6) lines of protection in a differential mode configuration as depicted in
Figure 1.
Circuit connectivity is as follows:
Pins 1, 2, 4, 5, 6 and 7 are connected to the datalines.
Pin 8 is connected to ground.
Pin 3 is connected to the databus.
CIRCUIT BOARD LAYOUT RECOMMENDATIONS
Circuit board layout is critical for Electromagnetic Compat-
ibility (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 induc-
tance.
Ground planes should be used whenever possible.
For multilayer PCBs, use ground vias.
