This product provides unidirectional protection, with a surge capability of 200 Watts PPP per line for an 8/20µs waveform and ESD protection > 25 kilovolts. UNIDIRECTIONAL COMMON-MODE CONFIGURATION (Figure 1) The PSMF Series provides up to four (4) lines of protection in a common-mode configuration as depicted in Figure 1. Circuit connectivity is as follows: ✔ ✔ ✔ ✔ ✔ I/O 1 is connected to Pin 1. I/O 2 is connected to Pin 3. I/O 3 is connected to Pin 4. I/O 4 is connected to Pin 5. Pin 2 is connected to ground. Figure 1 - Unidirectional Configuration Common-Mode I/O Port Protection I/O 4 I/O 3 5 4 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. 1 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. 05123.R9 10/05 2 3 I/O INTEGRATED CIRCUIT CIRCUIT BOARD LAYOUT RECOMMENDATIONS I/O 2 I/O 1 4 www.protekdevices.com PSMF05 thru PSMF24 PACKAGE OUTLINE & DIMENSIONS PACKAGE OUTLINE D SC70-5L E 5 4 1 2 PACKAGE DIMENSIONS 0° - 8° K 3 L J F A B C D E F G J K L M M B A G C MOUNTING PAD 4 0.020 0.051 0.026 0.068 0.024 0.044 0.092 2.15 1.35 1.00 0.30 1.10 0.25 2.15 0.10 0.46 0.074 0.045 0.031 0.006 0.0255 BSC 0.0512 BSC 0.031 0.003 0.074 0 0.010 0.084 0.055 0.040 0.012 0.043 0.010 0.084 0.004 0.018 1.
