This product series provides unidirectional & bidirectional protection, with a surge capability of 500 Watts PPP per line for an 8/20µs waveform and ESD protection > 40 kilovolts. BIDIRECTIONAL COMMON-MODE CONFIGRUATION (Figure 1) Figure 1 - Common-Mode I/O Port Protection Two PSOTxxLC devices, when used in paralell, provide protection in a common-mode configuration as depicted in Figure 1. I/O LINE Circuit connectivity is as follows: ✔ ✔ ✔ ✔ ✔ I/O Line is connected to Device 1, Pin 1. I/O Line is connect to Device 2, Pin 2. Device 1, Pin 2 is connected to ground. Device 2, Pin 1 is connected to ground. Device 1 & 2, Pin 3 is not connected. 1 2 3 3 2 1 BIDIRECTIONAL DIFFERENTIAL-MODE CONFIGRUATION (Figure 1) In addition, two PSOTxxLC devices, when used in paralell, provide protection in a differential-mode configuration for Ethernet applications as depicted in Figure 2. Circuit connectivity is as follows: I/O Line 1 is connected to Device 1, Pin 1. I/O Line 1 is connect to Device 2, Pin 2. I/O Line 2 is connected to Device 1, Pin 1. I/O Line 2 is connect to Device 2, Pin 2. Device 1 & 2, Pin 3 is not connected. 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. 05066.R6 3/07 Figure 2 - Differential-Mode Ethernet Protection ETHERNET TRANSCEIVER ✔ ✔ ✔ ✔ ✔ GND 4 I/O 1 1 2 3 2 3 1 I/O 2 www.protekdevices.com PSOT03LC thru PSOT36LC SOT-23 PACKAGE OUTLINE & DIMENSIONS PACKAGE OUTLINE SOT-23 A L 0º - 10º 3 B 1 S PACKAGE DIMENSIONS 2 K J MILLIMETERS MIN MAX DIM V A B C D G H J K L S V G C D H 2.80 1.20 0.89 0.37 1.78 0.013 0.085 0.45 0.89 2.10 0.45 3.04 1.40 1.11 0.50 2.04 0.100 0.177 0.60 1.02 2.50 0.60 INCHES MIN MAX 0.1102 0.0472 0.0350 0.0150 0.0701 0.0005 0.0034 0.0180 0.0350 0.0830 0.0177 0.1197 0.0551 0.0440 0.0200 0.0807 0.0040 0.0070 0.0236 0.0401 0.0984 0.0236 NOTES MOUNTING PAD 1. 2. 3. 4. 0.037” (0.95mm) Dimensioning and tolerances per ANSI Y14.5M, 1985.
