PSR05
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 PPP 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
VBus
Circuit board layout is critical for Electromagnetic
Compatibility (EMC) protection. The following
guidelines are recommended:
D+
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.
