This product series has a surge capability of 500 Watts PPP per line for an 8/20s 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.
