APPLICATION NOTE
The PSR05 is a low capacitance, bidirectional TVS array that is 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 waveform and offers ESD protection > 25kV.
COMMON-MODE CONFIGURATION (Figure 1)
Ideal for use in USB applications, two PSR05 devices provides up to two(2) lines of protection(per device) in a common-mode configuration as
depicted in Figure 1.
Circuit connectivity is as follows:
Pins 2 and 3 are connected to the datalines.
Pin 1 is connected to ground.
Pin 4 is connected to the databus.
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.
