This product series provides both unidirectional and bidirectional protection, with a surge capability of 500 Watts PPP per line for an 8/20µs waveform and ESD protection > 40kV.

RX R 1 4 2 3 RJ-45 ETHERNET TRANSCEIVER Figure 2 - Bidirectional Configuration Differential-Mode Ethernet Protection R TX 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. 05091.R11 2/07 4 www.protekdevices.com PSLC03 thru PSLC24C SOT-143 PACKAGE OUTLINE & DIMENSIONS PACKAGE OUTLINE SOT-143 A G L PACKAGE DIMENSIONS J S B MILLIMETERS MIN MAX DIM A B C D F G H J K L R S K D F H C R MOUNTING PAD DIM Millimeters Inches 1 2 3 4 5 6 7 8 9 10 11 2.85 2.00 1.80 1.90 1.05 2.75 1.20 0.80 0.85 0.85 0.85 3.04 1.39 1.14 0.50 0.93 2.03 0.10 0.15 0.60 0.60 0.83 2.48 0.110 0.047 0.033 0.015 0.031 0.070 0.0005 0.003 0.018 0.0175 0.028 0.083 0.120 0.055 0.045 0.020 0.037 0.080 0.004 0.006 0.024 0.024 0.033 0.098 NOTES 1 TYPICAL 2.80 1.20 0.84 0.39 0.79 1.78 0.013 0.08 0.46 0.445 0.72 2.11 INCHES MIN MAX 1.
