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. Figure 1. Typical Common-Mode USB Protection VBus 1 4 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. ✔ 3 D- USB CONTROLLER ✔ 2 VBus D+ D- Ground planes should be used whenever possible. For multilayer PCBs, use ground vias.
