This product provides unidirectional and bidirectional protection; the device is connected as follows: BIDIRECTIONAL COMMON-MODE CONFIGURATION The WE05MFC WE05MFC provides up to four (4) lines of protection in a common-mode configuration as depicted in Figure 6. Circuit connectivity is as follows: I/O 1 is connected to Pin 3. I/O 2 is connected to Pin 1. I/O 3 is connected to Pin 6. I/O 4 is connected to Pin 4. Pin 5 is connected to ground. I/O 1 3 2 1 4 5 6 I/O INTEGRATED CIRCUIT I/O 2 I/O 3 I/O 4 Figure 6 Bidirectional Configuration Common-Mode I/O Port Protections 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. ©2008 WAYON Corporation www.way-on.com 4/5 WE05MFC WE05MFC SilicontrolTM Overvoltage Protection Products Outline Drawing SOT-563 PACKAGE OUTLINE E1 A1 e L D DIMENSIONS b SYMBOL INCHES MILLIMETER MIN MAX 0.021 0.024 0.525 0.600 0.000 0.002 0.000 0.050 e MAX A1 E MIN A A 0.018 0.022 0.450 0.550 0.006 0.090 0.160 0.059 0.067 1.500 1.700 0.007 0.011 0.170 0.270 E1 0.043 0.051 1.100 1.300 E 0.059 0.067 1.500 1.700 L 0.004 b c c D 0.004 0.012 0.100 0.300 7°REF 7°REF X Notes DIMENSIONS DIM INCHES MILLIMETERS Z 0.89 0.020TYP 020TYP 0.51 TYP X 0.0118 0.3 Y P 1.91 0.0350 P Y 0.0752 G G Z 0.0201 1.
